Rollup merge of #139178 - apiraino:remove-cjgillot-automated-assighment, r=cjgillot

Remove cjgillot from automated review assignment

As discussed [on Zulip](508540539).

To be clear, this is not a value judgement, it's just a way to improve our fairness when assigning reviews, trying to find a balance between leaving time to Rust contributors review on their terms and availability and avoid having PRs waiting for too long.

> [!IMPORTANT]
> This is not a final decision! Rust contributors are free to re-add themselves back to the active review rotation (if they feel like it) once they have more availability.
