Supabase feature downloads correct cli

[Rinze-Smits]

• Supabase cli provides two types of releases, we should make sure to pick the right one.
• Supabase cli has many prerelease versions, a filter was added to make sure those don't get downloaded as they often contain unfinished work. Unfortunately this means you also can't ask for a prerelease version specifically. Maybe when nanolayer uses the normal github api to fetch latest version (which automatically filters prereleases and drafts) this can be reverted.
• Supabase cli release assets have two version of the assets, one with version number in the file name and one without. gh-release can't handle multiple valid results so a filter on the asset picks the one with version number (because old releases only have that as asset)
