New Issue: I/O Module: Deprecate ''unlink'' function

20268, "benharsh", "I/O Module: Deprecate ''unlink'' function", "2022-07-20T02:10:18Z"

This issue concerns the unlink function in the IO module:

proc unlink(path:string) throws

This function wraps the unix unlink function, and should be removed in favor of FileSystem.remove.

Notably, this will require a change to the IO primer.
