Add API Documentation Generation and Deployment

[rachfop]

Description:

This pull request adds the capability to generate API documentation using pydoctor and automatically deploy it to GitHub Pages.

Changes

• Added a new GitHub Actions workflow (CI-api-docs.yml) to generate and deploy API documentation.
• Updated the pydoctor command in the workflow to match the project's folder structure and configuration.
• Configured the workflow to generate API documentation on every push to the repository.

Deployment to GitHub Pages

Please note that after merging this pull request, additional steps are required to enable GitHub Pages for the repository:

1. Go to the repository settings on GitHub.
2. Navigate to the "Pages" section.
3. Under "Source", select the "gh-pages" branch and click "Save".
4. Re-run the apidocs workflow to trigger the first deployment.

As mentioned in the actions-gh-pages documentation, the first workflow run won't actually publish the documentation to GitHub Pages. GitHub Pages needs to be enabled afterwards in the repository settings, select the gh-pages branch, then re-run your workflow.

Once the deployment is complete, the API documentation will be accessible at:

https://runpod.github.io/runpod-python/

Preview

You can preview the generated API documentation by running the pydoctor command locally:

pydoctor \
    --project-name=RunPod \
    --project-version=your-project-version \
    --project-url=https://github.com/runpod/runpod-python \
    --html-viewsource-base=https://github.com/your-username/your-repo/tree/your-branch-or-tag \
    --make-html \
    --html-output=docs/api \
    --project-base-dir="." \
    --docformat=restructuredtext \
    --intersphinx=https://docs.python.org/3/objects.inv \
    ./runpod

The generated documentation will be available in the docs/api directory.

Please review the changes and let me know if you have any questions or suggestions.
