Update runners, rust, and dependencies (#724)

#719 is failing tests due to requiring a newer version of rust than we
currently specify. This PR updates to 1.85.1 and sets the edition to
2024.
I've also updated dependencies and runner images, using the ubuntu arm
runner which removes the need for qemu and other hacks.

Closes #719.
