Use Rust 1.83 in CI and simplify CI setup

This tweaks our CI setup in GitHub Actions to always use Rust
1.83, the current stable version, rather than a nightly release.
This should help to avoid [surprising red builds][1] due to changes
in Rust.

As part of this change, I've also dropped the use of deprecated
`actions-rs` actions and done some other refactoring of the CI
pipelines.
