Remove orphaned content from examples.md template

The previous commit accidentally included generated content that was
outside the proper OUTPUT sections. This commit removes the orphaned
markdown examples and keeps only the template structure with PLACEHOLDER
text that gets replaced during CI builds.

-### Idea 3: Generating Markdown Tables
-
-Use the `pandas` library to create a Markdown table from a DataFrame. The following example demonstrates how to create a table with random data:
-
-```python
-import pandas as pd
-import numpy as np
-
-# Generate random data
-np.random.seed(42)
-data = np.random.randint(1, 101, size=(5, 3))
-
-# Create a DataFrame and column names
-df = pd.DataFrame(data, columns=["Column A", "Column B", "Column C"])
-
-# Convert the DataFrame to a Markdown table
-print(df.to_markdown(index=False))
-```
-
-Which is rendered as:

-<!-- OUTPUT:START -->
-<!-- PLACEHOLDER --> Output is generated during CI build. We don't commit generated content to keep docs copyable and avoid recursion. See docs/docs_gen.py
-<!-- OUTPUT:END -->
-
-### Idea 4: Generating Visualizations
-
-Create a visualization using the `matplotlib` library and save it as an image. Then, reference the image in your Markdown file. The following example demonstrates how to create a bar chart.
-
-Using a triple-backtick code block:
-
-<!-- CODE:SKIP --> <!-- This is here otherwise the next example gets executed -->
-```python
-import matplotlib.pyplot as plt
-import io
-import base64
-from urllib.parse import quote
-
-# Example data for the plot
-x = [1, 2, 3, 4, 5]
-y = [2, 4, 6, 8, 10]
-
-# Create a simple line plot
-plt.plot(x, y)
-plt.xlabel("X-axis")
-plt.ylabel("Y-axis")
-plt.title("Sample Line Plot")
-
-# Save the plot to a BytesIO buffer
-buf = io.BytesIO()
-plt.savefig(buf, format='png')
-plt.close()
-
-# Encode the buffer as a base64 string
-data = base64.b64encode(buf.getvalue()).decode('utf-8')
-
-# Create an inline HTML img tag with the base64 string
-from urllib.parse import quote
-img_html = f'<img src="data:image/png;base64,{quote(data)}" alt="Sample Line Plot"/>'
-
-print(img_html)
-```

-<!-- PLACEHOLDER --> Output is generated during CI build. We don't commit generated content to keep docs copyable and avoid recursion. See docs/docs_gen.py
-<!-- OUTPUT:END -->
-
-> **NOTE**: This output is disabled here because GitHub Markdown doesn't support inline image HTML. This will work on other Markdown renderers.

-### Idea 5: Generating a table from CSV data
-
-Suppose you have a CSV file containing data that you want to display as a table in your Markdown file.
-You can use `pandas` to read the CSV file, convert it to a DataFrame, and then output it as a Markdown table.
-
-Using a triple-backtick code block:
-
-```python
-import pandas as pd
-csv_data = "Name,Age,Score\nAlice,30,90\nBob,25,85\nCharlie,22,95"
-with open("sample_data.csv", "w") as f:
-    f.write(csv_data)
-df = pd.read_csv("sample_data.csv")
-print(df.to_markdown(index=False))
-```
-
-Which is rendered as:
-
-<!-- OUTPUT:START -->
-<!-- PLACEHOLDER --> Output is generated during CI build. We don't commit generated content to keep docs copyable and avoid recursion. See docs/docs_gen.py
-<!-- OUTPUT:END -->
-
-### Idea 6: Displaying API data as a list
-
-You can use `markdown-code-runner` to make API calls and display the data as a list in your Markdown file.
-In this example, we'll use the `requests` library to fetch data from an API and display the results as a list.
-
-Using a hidden code block:
-
-<!-- CODE:SKIP --> <!-- This prevents the example below from getting executed -->
-```markdown
-<!-- CODE:START -->
-<!-- import requests -->
-<!-- response = requests.get("https://jsonplaceholder.typicode.com/todos?_limit=5") -->
-<!-- todos = response.json() -->
-<!-- for todo in todos: -->
-<!--     print(f"- {todo['title']} (User ID: {todo['userId']}, Completed: {todo['completed']})") -->
-<!-- CODE:END -->
-<!-- OUTPUT:START -->
-<!-- PLACEHOLDER --> Output is generated during CI build. We don't commit generated content to keep docs copyable and avoid recursion. See docs/docs_gen.py
-<!-- OUTPUT:END -->

-
-### Idea 7: Run a Rust program
-
-We can use `markdown-code-runner` to write Rust code to a file and then a hidden bash code block to run the code and display the output.
-
-The code below *is actually executed*, check out the [`README.md` in plain text](https://github.com/basnijholt/markdown-code-runner/blob/main/README.md?plain=1) to see how this works.
-
-```rust
-fn main() {
-    println!("Hello, world!");
-}
-```
-
-Which when executed produces:
-
-<!-- CODE:BASH:START -->
-<!-- echo '```' -->
-<!-- rustc main.rs && ./main -->
-<!-- echo '```' -->
-<!-- CODE:END -->
-
-<!-- OUTPUT:START -->
-<!-- PLACEHOLDER --> Output is generated during CI build. We don't commit generated content to keep docs copyable and avoid recursion. See docs/docs_gen.py
-<!-- OUTPUT:END -->
-
-These are just a few examples of how you can use Markdown Code Runner to enhance your Markdown documents with dynamic content. The possibilities are endless!
