Subject: [PATCH] Don't attempt to use `find` crawler on Windows

Summary:
This replicates the [hotfix](https://github.com/facebook/metro/commit/370301981b8e5a92e072e5a2323e9be3308a2cdf) released in 0.73.7, to address an issue whereby Metro would fail to crawl files on Windows for non-Watchman MinGW users.

A more substantial fix should follow - IMO, we should remove this `find` crawler completely unless it's more performant in some circumstance. This diff just brings in the quick, least-intrusive fix to get `main` up to parity with `0.73.x`.

Closes: https://github.com/facebook/metro/issues/914
