Simple Voice Chat Discord Bridge

• Fixed the infamous issue of needing a newer glibc than is available on old LTS Linux distributions (#144, #63, #106)
  • The minimum glibc version is now 2.26; if anyone needs lower than this, just make a GitHub issue. However, note that glibc 2.26 was released in 2017...
• Renamed the Rust log file (previously logs/voicechat-discord.log) to logs/voicechat-discord.txt.
• Updated various URLs to use the GitLab repo instead of the GitHub repo.
• Fixed a copy of slf4j being included in the jar.
• Moved SVC version checking code to Paper because it is unnecessary on Fabric.
• Fixed checking if a player is an operator if the server has a non-default op permission level configured on Fabric.
• Refactored Fabric codebase to use source templates when version specific code is needed instead of a messy version specific class.
• Fabric versions that produce an identical jar will now be combined to reduce the number of jars that are built.
• Fixed Fabric API dependency on 1.16.5 by using the legacy mod ID.
• Fixed Folia not being marked as supported.
• Added support for 1.21.11.
