Upstream changes (#717)

* Perform part of the move of //fast to //perf (#1377)

This re-adds a deprecated `//fast` and moves the current logic to
`//perf`. Later `//perf` will have its syntax reworked, when Piston
finally supports sub-commands properly!

* Names via Translation (#1268)

* Deprecate BiomeRegistry, etc.

* Update some libraries, e.g. text

* Move to new translation renderer

* Revert "Deprecate BiomeRegistry, etc."

This reverts commit 59a5d6c92aec52739a8dc68ac3d23898af7593dd.

This was not a good idea for potential mod shenanigans.

* Move BiomeData#getName to BiomeRegistry, use i18n

* Use getRichName instead of getName

* Implement getRichName for NullBiomeRegistry

* Add getRichName for blocks

* Relocate net.kyori.minecraft

* Update adapters for getRichBlockName

* Add getRichName for items

* Update adapters for getRichItemName

* Update adapters JAR for merge

(cherry picked from commit cfd26253b6fb59ff6c65a0157a6780be7db4ea5a)

* Follow-up fixes for 92f8776796

* Don't send deprecation warning and improve info message

* Fix click command for perf box

(cherry picked from commit 7ee60060c31df2f8b41212b430a0875312189339)

* update R3 adapter§
