Skip `.DS_Store` files when looking for extension directories (#10046)

This PR makes it so `.DS_Store` files are skipped when trying to load
extension directories.

Previously it would fail and log an error.

Release Notes:

- Fixed an issue where the presence of a `.DS_Store` file in the
extensions directory would produce an error in the logs.
