Update to KordEx v2

[gdude2002]

This PR makes the following changes:

• Update to KordEx v2
• Remove @WiredPlugin usage and replace it with the plugin { } block in the Gradle plugin configuration
• Remove the mappings extension, since @sschr15 is still AWOL and hasn't OK'd it for KordEx v2's licensing
• Configure the new /about command
• Set the data collection mode to "Minimal" (decided by @OroArmor)
• Fix the formatting in the Minecraft patch notes extension b/c it was pissing me off (format blockquotes and italics, triple embed length)
  • This also includes an "update" command that requests that a message be edited with the patch notes of the given version
  • I also fixed the permissions for the /mc management subcommands, as previously they required both the mod role and the admin perm, when they should've accepted either

You should use the dev Gradle task to launch the bot in development going forward, instead of run

For more information on what changed in v2, make sure you read up!

As usual, I don't have an environment to test this in. It was a pretty painless update, but someone should still test it before merging.

BEFORE YOU MERGE CHECKLIST

• Test the bot
  • Update your IDE config to use the dev Gradle task instead of run for testing

Removing the mappings feature does make cozy quite a bit less useful IMO

That change was also made at the request of the infra team, who are currently working with limited machine resources.

Please note that we've run into a problem with how KSP generates its tasks - it seems to be a timing issue created by KSP, and I'm still looking for a way to work around it in the KordEx plugin.

[gdude2002]

This problem has been fixed.

I fixed the patch notes. Merry Chrysler.

I've tested the bot and it seems to be working as intended. A couple of notes:

• You've already made the necessary IDE updates for IDEA users, right?
• I've noticed that there's a lot of line breaks in between headings with the mc command. Is this new behaviour?

I'm an IDEA user and things seem to work fine?

I've noticed that there's a lot of line breaks in between headings

There are no additional line breaks iirc, it's just that it uses actual markdown headings now - feel free to remove one of them if you think it'd work better
