[BUG] Precompilation failing on GitHub Actions (MacOS)

[juliohm]

Details

The precompilation on MacOS is failing consistently on GitHub Actions. It seems to be related to GR.jl + Plots.jl:

ERROR: LoadError: LoadError: InitError: Evaluation into the closed module `GR` breaks incremental compilation because the side effects will not be permanent. This is likely due to some other module mutating `GR` with `eval` during precompilation - don't do this.

Your GR installation is incomplete. Rerunning build step for GR package.
┌ Info: Switching provider to GR due to error in depsfile
└   depsfile = "/Users/runner/.julia/packages/GR/qSS8e/deps/deps.jl"

The contents of deps.jl is import GR_jll so that indicates a problem with GR_jll on Mac in Github Actions.

Try setting the environmental variable JULIA_GR_PROVIDER to GR for that platform. That should fix the issue in Github Actions.
