SkAnalyzer v2.0.0-beta.1

Finally, after a few months of work, here we are - SkAnalyzer 2.0.0-beta.1!

Changes:

• Add plugin class rewriter (fixes issues with Material.values() returning also legacy materials)
• Enhance SkBee (nbt syntax elements!) and other addons support
• Bump Skript to 2.11.2
• Bump MockBukkit version to 1.21.5
• A lot of internal api changes, other small fixes and enhancements (like bootstrap system)
• Remove working directory property - now actual working directory is used instead

and more!
