Add version input handling for manual workflow triggers in CI

This commit enhances the GitHub Actions workflow by adding an input parameter for the package version during manual triggers. It includes logic to extract the version from release tags or use the provided input, ensuring that the version is set correctly for releases. This change improves the flexibility and usability of the publishing process.
