fix(cli): resolve latest CLI release when GitHub latest points to non-CLI tag (#12148)

* fix(cli): resolve latest CLI release when install script hits non-CLI tag

The GitHub releases/latest endpoint can point to non-CLI releases
(e.g., jetbrains/v7.0.4), whose tag prefix doesn't match the existing
version regex. Query the paginated releases endpoint, pick the first
tag starting with 'v', and use that version for both display and the
download URL instead of trusting releases/latest.

Closes #12125

* fix(cli): select stable installer release
