feat(loader): Add dataframe/huggingface specific classes

[fabiofelix]

The following PR is about:

• [ x ] [FEAT] LoaderFactory.build only supports file sources #72

It unifies LoaderBase interface by:

1. Replace load_data_from_file with load method
2. Create a FileLoader class that inherits LoaderBase. Therefore, CSVLoader, ParquetLoader, and ShapefileLoader inherit this class
3. Create DataFrameLoader and HuggingFaceLoader, which inherit LoaderBase, and moving specific codes from LoaderFactory.
4. Refactor of LoaderFactory code, mainly build and load methods.
5. Create/edit unit tests.
6. Update the documentation and examples.

Now, it is possible to use HuggingFace (or dataframe) in a pipeline in the same way as file loaders, calling the factory method build.
Before, the user should've retrieved data from HuggingFace, saved it as a file, and used a file loader with the pipeline.

Great PR! The main improvement is that Hugging Face data can now be used directly in the pipelines without converting it to a CSV first—this removes redundancy, which is excellent.
Just one minor fix: the docs/copy_of_examples folder should be removed, as it seems to have been committed by mistake. Apart from that, everything looks ready to merge.

If @fabiofelix did change the examples he needs to push the copy_of_examples in docs otherwise the "notebooks" are not forwarded to the documentation; just in case ✅

Let me have a Quick Look at the PR I have 5" before merging guys please

Amazing PR @fabiofelix ! Nothing of a big deal to change just to convince me this is the right way / expected, let me know!

Cheers

Brilliant PR! Approving on my side of the table! Thanks for this great one @fabiofelix!

Next time, let's try to have a separate commit when you are changing things a little outside the scope of the PR, such as the viz. color palettes in the examples, so that this commit can have a description explaining why the change was made to avoid confusion, please.

I'll let @soniacq merge once she approves the PR 🫡

Cheers!
