Switch to modmuss50's Mod Publush Plugin

[srnyx]

Replace mc-publish with https://github.com/modmuss50/mod-publish-plugin

Since it's a Gradle plugin, we can easily supply everything in the build file rather than a separate workflow file.

Optionally, we can also use Blossom to insert all of the platform details into the code, which can then be used in the updatePlatforms PluginOptions. Thus preventing identifiers being duplicated across files.

We may also be able to take this a step further by integrating into https://srnyx.com/projects/data, but that's a whole nother thing...

No matter what we do, we can easily integrate everything into Gradle Galaxy :)

Maybe also https://github.com/HangarMC/hangar-publish-plugin

mod publish plugin basically done, there are just a few issues with it, only one of which really matters:

• CurseForge publishing errors with plugin-based loaders modmuss50/mod-publish-plugin#112 (needs to be fixed!!)
• Add Hangar platform support modmuss50/mod-publish-plugin#113 (can just use hangar-publish-plugin for now instead)
• Add additional files type setting modmuss50/mod-publish-plugin#114 (only matters for annoying api, and still doesnt really matter)

already integrated into gradle galaxy and common workflow tools
