This PR enables the job that requires running on a machine with a GPU. It will run on a g6e.2xlarge runner.

I see that not only the job that I'm migrating to self-hosted runners, but also Clippy and Test in release mode on MacOS have started failing now with the same error:

Last month they were still passing on the default branch: https://github.com/filecoin-project/rust-filecoin-proofs-api/actions/runs/15213629917

@vmx Do you have an idea why that might be?

Things should work, but the current master patches the rust-fil-proofs crates to point to the master branch:

rust-filecoin-proofs-api/Cargo.toml

Lines 32 to 36 in b06f9fb

	[patch.crates-io]
	filecoin-proofs = { git = "https://github.com/filecoin-project/rust-fil-proofs" }
	fr32 = { git = "https://github.com/filecoin-project/rust-fil-proofs" }
	filecoin-hashers = { git = "https://github.com/filecoin-project/rust-fil-proofs" }
	storage-proofs-core = { git = "https://github.com/filecoin-project/rust-fil-proofs" }

.

As there was a release of rust-fil-proofs, this repo should be updated to use the released version. So I suggest that the current maintainers update to those versions and the we'll see if things still fail.
