Use the minecraft-dependencies BOM for deps

[Matyrobbrt]

This PR switches us from using a version of GSON and SLF4J defined in the gradle.properties for the coremods and Gradle plugin projects to using the minecraft-dependencies platform to keep the versions in sync.

The PR also removes the explicit commons-lang3 dependency as the server and client version difference is no longer present in 1.21.4
