Subject: [PATCH] Add locale renames for Hebrew and Indonesian on Windows

Windows does not fully respect ISO 639-1 like other systems,
so we have to override its locale values for those languages.

Also added comments to document the locale provenance.

(cherry picked from commit 0c7bed45c49b19bf49b2f2f462937fe14b26c3bb)
