Here, try to address #1260 by making up migrations with `TargetVersion` no longer error if we find that the database has already reached that target version. These now return idempotently instead as a user convenience. Down migrations with `TargetVersion` already worked with this way, so although we add a test case to verify this, we don't have to do anything else. Fixes #1260.

| ⚠️ **Breaking API change:** `rivermigrate.Migrator.Validate` and `rivermigrate.Migrator.ValidateTx` now take a `*rivermigrate.ValidateOpts` parameter. Pass `nil` to preserve previous behavior. We normally endeavor not to make any breaking API changes, but this one will keep the API in a much nicer state, and is on an ancillary function that most installations won't be using.

Think "changed" is actually a bit more appropriate for both these changelog entries.
