Long build time for `just`

[ekilmer]

just, a rust-based tools installed using Cargo, can take a long time to build on GitHub Actions runners.

We should look into a way to download pre-built tools in a way that supports multiple platforms (Linux, Windows, macOS) to speed up this installation process.

just has a Releases page with pre-built binaries, so we could pull from there, as long as the naming stays somewhat consistent.

extractions/setup-just#10
There's an open issue that looks like it has momentum to get this fixed so we can just use the setup-just action.

@oldsj Looks like that PR was merged into v1.6.0 (Changes: extractions/setup-just@v1.5.0...v1.6.0)
