docs: Update branding and introduce custom layout for docs site

- Renamed the title in `index.md` to "pdfRest API Toolkit Python SDK."
- Added a custom sidebar separator via `brand.css` for better navigation
  grouping.
- Configured `mkdocs.yml` to use a new `custom_dir` for overrides and branding.
- Introduced `overrides/main.html` to update the page `<title>` dynamically.
