Remove deprecated annotations from javadocs

This adds on to some of the previous commits removing Bukkit's deprecation of name-based methods. Some of the methods that were undeprecated stayed deprecated because of the deprecated annotations in the javadocs.

I do realize that I could have modified https://github.com/SpigotMC/Spigot/blob/master/Bukkit-Patches/0025-Remove-deprecation-on-some-player-lookup-methods.patch, but I don't know how (googling didn't work, if someone is willing to help me that would be amazing).

Thanks,
