1.16.2 Release (#4123)

Browse Source 
PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues.

Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong.

This is now resolved.

Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me.

Please as always, backup your worlds and test before updating to 1.16.2!

If you update to 1.16.2, there is no going back to an older build than this.
