Why do you even want the issue number in the commit title? I find that super annoying and unfortunately GitHub kind of forces it on you if you use merge queues.
It's fine for it to be in the description.

When working in big teams, it can be very hard to increase the usefulness of commit messages. On the other hand, enforcing inclusion of a Jira issue key in commit messages is easy to implement. Relying on issue tracker descriptions can be a difficult proposition as well. Quality of individual ticket descriptions can be low; depending on how responsibility for maintenance is handled, the bug tracker migrations can sometimes be handled improperly and information can be more easily lost than in a Git log.
