chore: update to Rust 1.90 (#2916)

<!-- Thank you for making a PR! Bug fixes are always welcome, but if
you're adding a new feature or changing an existing one, we'd really
appreciate if you open an issue, post on the forum, or drop in on
Discord -->

## Checks
- [X] I am happy for maintainers to push small adjustments to this PR,
to speed up the review cycle
- [X] I have checked that there are no existing pull requests for the
same thing

Hopefully this one is mergeable as is, unlike the 1.89 upgrade.

Fixes: #2915
