Fix: correct version 0.x selection displaying latest version

[Priyansu-Panda]

Summary

Corrects a bug where choosing version 0.x from the version dropdown showed the most current stable release rather than the intended 0.x release.

Changes Made

• Changed version filtering logic to correctly identify and display the chosen 0.x version.
• Included validation to guarantee 0.x returns the correct release notes.
• Reworked handling of versions to avoid fallback to the current version.

Testing Details

• Confirmed that choosing 0.x now shows the proper release notes.
• Tested on varying channels (stable, prerelease, and nightly).
• Validated that invalid or unsupported versions redirect to the proper fallback page.
