Bump to mark as up-to-date

Package was marked as out-of-date because I didn't get back to @xiota
within four days, bumping to remove out-of-date flag while we discuss

> xiota flagged python39 out-of-date on 2023-06-09 (UTC) for the following reason:
>> Needs `tk` added to `makedepends`. Flagging because no response to comment.
