Add $shallow arg to RoomShareProvider::getSharesInFolder

A new `$shallow` argument was introduced to `IShareProvider::getSharesInFolder` in NC25 by nextcloud/server#31728.

This PR adds this new argument and the necessary changes to make it work based on this example https://github.com/nextcloud/server/pull/31728/files#diff-dee1351696d7eae959761edf66c8e5a9052e28be73319733d857a9ab2d9fc967=
