Therefore, the bot will modify the PR title to match the new issue the user wants to add, resulting in the removal of the draft state of the PR.

Is there a better place to remove the `Draft:` prefix? I'm wondering if it would be possible to generalize it by removing the "Draft:" prefix similarly to how the optional `JDK-` prefix is removed? That way it would be parsed as a valid issue for the purpose of listing the BugID + Bug tltle in the Description, checking for a CSR, etc.
