[skip ci] github: Add dependabot configuration and update workflows

- Added dependabot configuration for GitHub Actions and Docker.
- Updated docker_manifest.yml to include ARM64 build job.
- Modified on_pr.yml and on_push.yml to comment out unused platforms.
- Updated Containerfile to define fork repository arguments.
- Added LICENSE file with MIT License.
- Created action.yml for Circuitpython Port Builder Composite Action.
- Enhanced entrypoint.sh for better build and release handling.

+
+## Introduction
+
+`action-circuitpython-builder` is a GitHub Action designed to build CircuitPython ports. It supports multiple platforms and targets, enabling developers to quickly build and release CircuitPython projects.
+
+## Features
+
+- Supports multiple CircuitPython platforms (e.g., espressif, nordic).
+- Supports build and release targets.
+- Allows specifying single or multiple boards for building.
+
+## Usage
+
+### 1. Reference in Workflow
+
+Add the following to your GitHub Actions workflow file:
+
+```yaml
+yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+
+    steps:
+      - name: Checkout repository
+        uses: actions/checkout@v3
+
+      - name: Build CircuitPython
+        uses: fobe-projects/action-circuitpython-builder@v1
+        with:
+          cpy_platform: "espressif" # Required, specify the platform
+          cpy_target: "build"       # Optional, defaults to build
+          cpy_board: "esp32"        # Required when cpy_target is build
+```
+
+### 2. Input Parameters
+
+| Parameter Name  | Required | Default  | Description                                   |
+|-----------------|----------|----------|-----------------------------------------------|
+| `cpy_platform`  | Yes      | None     | CircuitPython platform (e.g., espressif, nordic). |
+| `cpy_target`    | No       | `build`  | Target to run, options are `build` or `release`.   |
+| `cpy_board`     | No       | None     | Required when `cpy_target` is `build`, specify the board. |
+| `cpy_boards`    | No       | None     | Required when `cpy_target` is `release`, specify multiple boards. |
+
+### 3. Examples
+
+#### Build a Single Board
+
+```yaml
+yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+
+    steps:
+      - name: Checkout repository
+        uses: actions/checkout@v3
+
+      - name: Build CircuitPython for ESP32
+        uses: fobe-projects/action-circuitpython-builder@v1
+        with:
+          cpy_platform: "espressif"
+          cpy_target: "build"
+          cpy_board: "esp32"
+```
+
+#### Release Multiple Boards
+
+```yaml
+yaml
+jobs:
+  release:
+    runs-on: ubuntu-latest
+
+    steps:
+      - name: Checkout repository
+        uses: actions/checkout@v3
+
+      - name: Release CircuitPython for multiple boards
+        uses: fobe-projects/action-circuitpython-builder@v1
+        with:
+          cpy_platform: "nordic"
+          cpy_target: "release"
+          cpy_boards: "board1,board2,board3"
+```
+
+## Notes
+
+- When `cpy_target` is `build`, the `cpy_board` parameter must be provided.
+- When `cpy_target` is `release`, the `cpy_boards` parameter must be provided.
