remove snippets for float and int types

[xdBronch]

these have always been extremely annoying to me when trying to tab thru the arguments of function snippets since i accidentally end up putting some random int type instead of just a number like i want. also theyre 2-4 characters, youll almost certainly type what you want faster than waiting for and reacting to completion. i asked on the zig discord and some people agreed, please leave any thoughts
