Better customization of featured versions

[triphora]

As described in one of the Discord tags, this is how the featured version system currently works:

For most intents and purposes, the automatic featuring system for versions on projects is sufficient. Automatically featured versions are based upon major game version releases (1.15.2, 1.16.1, 1.16.5, 1.17.1, etc.) as well as on mod loader (if you have a 1.18.2 version for both Fabric and Forge, both will be featured).

If you have a single version that is manually featured, the auto-featuring system will not work. Thus, we do not recommend manually featuring any version.

However, the system is not applicable to all projects; this should be the default system, not the one everyone uses. Project authors should be able to select which attributes they want their featured versions to be based on.

Game versions

With Mojang's recent announcement that minor releases would become more frequent, we've started having issues with lots of versions having to be marked as major. Currently, this is the list of major versions:

curl -s https://api.modrinth.com/v2/tag/game_version | jq -r '[.[] | select(.major==true) | .version] | join(", ")'

1.19.4, 1.19.3, 1.19.2, 1.19, 1.18.2, 1.17.1, 1.16.5, 1.16.1, 1.15.2, 1.14.4, 1.13.2, 1.12.2, 1.11.2, 1.10.2, 1.9.4, 1.8.9, 1.7.10, 1.6.4, 1.5.2, 1.4.7, 1.3.2, 1.2.5, 1.1, b1.7.3

Every 1.19 version besides 1.19.1 is featured! The vast majority of mods will not support 1.19.3, .2, or .0 if they support .4, but for compatibility with those mods that haven't updated, we still have all of these selected for all projects. Authors should be able to select which game versions they want featured.

Loaders

Loaders probably should not be included in the customization, but there could be certain use cases where it is useful. For example, if a project supports only Fabric but there were previously experimental Forge versions (ex. Terra), these could be hidden from being featured.

Version type / release channel

Some authors do not want Alpha and/or Beta versions featured.

Manual override

As with current featured versions, there should be a way to manually override whether something should be featured or not featured per-version. However, simply force-featuring one version shouldn't unfeature all other versions, like it does now.
