Avoid checking `EXE001` and `EXE002` on WSL (#5735)

## Summary

Do not raise `EXE001` and `EXE002` if WSL is detected. Uses the
[`wsl`](https://crates.io/crates/wsl) crate.

Closes #5445.

## Test Plan

`cargo test`

I don't use Windows, so was unable to test on a WSL environment. It
would be good if someone who runs Windows could check the functionality.
