feat(release): enhance release management for extensions and update workflows

- Added support for multiple extensions in the release management system, specifying versioning for each extension in `.release-please-manifest.json`.
- Updated `release-please-config.json` to include configuration for individual extensions, allowing for more granular control over release types and versioning.
- Enhanced the README with detailed instructions on the release process, including automated and manual release steps.
- Removed outdated workflows related to CLI and multi-module releases, streamlining the CI/CD process.
- Updated GitHub Actions workflows to improve linting and testing processes, ensuring better code quality and consistency.
