Rename "Version" field to "Earliest Affected Version" in Bugzilla?

I don't think there's a need for a compromise that makes it even more
complicated. If we're not going to change the policy, making the
version field write-once for most users is fine for enforcing it imo,
and as long as we have the original reported version I don't think
it's worth adding a field for the last tested one.
