Remove Apache Commons Lang and unnecessary Guava usages

[MrMicky-FR]

• Remove Apache Commons Lang (was almost not used and is not really necessary with Guava)
• Remove unnecessary Guava usages like Lists.newArrayList() that can be replace with just new ArrayList<>()

Hi, any updates on this @RainWarrior ?
Thanks

Note that org.apache.commons.lang3.tuple.Triple is an abstract class and subclasses may be mutable, while the newly added Triple is immutable. However, that is probably fine since Minecraft only uses the immutable implementation?

Closing and reopening to rerun checks.

More than 4 years, that's a while! @peterix I've resolved the merge conflicts and the build/tests run locally for me, just the GitHub Actions workflow is awaiting approval from a maintainer :)
