feat(ci): run tests from all crates in workspace

[TomAFrench]

We're currently only running the tests in the default crates in each workspace, e.g. for noir-lang/noir we're not running any tests outside of the nargo crate.

We should definitely be checking the other crates for correctness (realistically we should be pushing test coverage further down so we rely less on expensive integration tests) so I've updated the workflows to run tests for every crate in the workspace.

@TomAFrench Will this crash when we aren't in a cargo-workspace? These are used in bb_wrapper which isn't a workspace.

I can't test on bb_wrapper directly atm (it's not wanting to build despite being on the mainframe), but I've checked in another non-workspace rust project and it worked fine.

Sounds good. I tested it in bb_wrapper and it seems to work. I also ran against Noir at https://github.com/noir-lang/noir/actions/runs/4233903932/jobs/7355474590 so I think it's good to go.
