Remove estebank from automated review assignment

[jieyouxu]

First of all, Esteban thanks for all the reviews 💙

I think you've been quite busy IRL recently, so I'm proposing to remove you from the automated review assignment to prevent randomly rolling compiler PRs to you until you have more availability. If this is just temporary, please close this PR!

This is 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.

Note

This only prevents randomly-rolled compiler PRs from being auto assigned to you, it does not prevent explicit r? assignments.

Please feel free to re-add yourself back to the active review rotation once you have more availability (if you feel like it).

• If you want, it's also possible to only opt-out of the general compiler review rotation (r? compiler) but keep e.g. r? diagnostics rolls.

triagebot.toml has been modified, there may have been changes to the review queue.
