Technical proposal

Following #490365 (closed)

Proposal

1. Implement a version selector feature on catalog resource pages.
2. When a specific version is selected:
   • Update the URL to reflect the chosen version (e.g., https://gitlab.com/explore/catalog/components/opentofu?version=0.27.0)
   • Display the page content, README, and component metadata corresponding to the selected version
3. By default, show the latest version when no specific version is selected
4. Ensure the version selector is consistent with existing designs for the feature
5. Update Publishing API to return the catalog URL containing the specific version (as of today it returns the URL without version).

Additional Notes

• This feature was previously included in the designs and should be prioritized for implementation
• The version selector will enhance user experience by allowing easy navigation between different versions of a catalog resource
• The version selector will act as a permalink for a specific version and it's returned by the Publishing API.
