Remove JohnTitor from review rotation

This removes `@JohnTitor` from the review rotation. I haven't seen any comments from them in this repository since February, and PRs that get assigned to them tend to sit a few weeks until someone notices. I see that they are still semi-active with libc, but I haven't been able to reach them on Zulip. If `@JohnTitor` wants to get back on the rotation in the future, they are welcome (I don't want to pressure them, their support in the past was much appreciated).
