Summary:

fs.rm function does not expand, so when using clean command, Metro files are not removed.

This is a follow-up PR to #2161 which solves this problem for Windows, but since fs.rm does not expand at all, it still doesn't work properly for macOS. Removing OS check in this solution does not solve the issue, probably because convertPathToPattern from fast-glob modifies the pattern from metro-* to metro-\*. This PR should work correctly on both operating systems.

Closes #2161

Test Plan:

  1. Find your OS temp directory (os.tmpdir())
  2. Use start command in any CLI app
  3. ls in the temp directory to verify any metro-* are listed
  4. Use clean command, select metro option and confirm
  5. ls in the temp directory again and verify all metro-* are gone
