Port to 1.21.4 and rework no vote data.

[MerchantPug]

Apologies if any file spacing is incorrect due to my IDE settings.

This PR:

• Ports the mod to 1.21.4.
• Reworks having no voting data.
  • Removed ModFest 1.21 test data from being built into the mod.
  • The game will no longer throw an exception upon not detecting categories or vote data. It will now have unique inactive voting handling if either one is not present.

Did you test ballotbox data via a data pack?

Hi, minor update for this PR.

We don't know whether Mod Garden will be running on 1.21.4 or 1.21.5, simply because we don't know when .5 will release.

If it releases in like March and if there's enough time to update mods, this PR will be changed to .5, so don't merge until we find out which version we're running on.

I kinda want everything in this PR except the 1.21.4 port - any chance of that?
