sig-storage: sync team members of external-snapshot-metadata with repo OWNERS

This commit syncs external-snapshot-metadata repo OWNERS
with the corresponding external-snapshot-metadata-maintainers
and external-snapshot-metadata-admins teams.

This is required in order for the missing members to be able to
create release branches and tag releases.
