Exclude sdkMemberVersionedDepTag from visibility enforcement

The implicit dependency from an unversioned sdk member to the snapshot
versions should be excluded from visibility enforcement as it provides
no benefit and would require snapshot members to be visible to their
original source modules which would complicate visibility handling.

Also, corrects a spelling mistake in sdkMemberVersionedDepTag.
