CI does not test "standard" configuration

[eschnett]

I think that the CI pipeline of MPI.jl tests only these two configurations:

• self-built OpenMPI with CUDA
• self-built OpenMPI with ROCM
  There are no tests with the default configuration, i.e. MPICH via MPICH_jll.

If I add such tests, would you prefer a github action or another buildkite group?

Uh?

MPI.jl/.github/workflows/UnitTests.yml

Line 31 in fd2c6c2

Silly me, didn't see that file.

Still, #933 only shows the buildkite tests. The unit tests do not show up. The "actions" tab doesn't show them either.

The problem was only that Project.toml wasn't included in the list of triggers of the unit test workflow: 812720b
