Subject: [PATCH] ci: bump Go to stable, refresh actions to v5

go.mod declares `go 1.25.5` but the workflow installed Go 1.20, which
errors on three-part version directives:

    go: errors parsing go.mod:
    /home/runner/work/gevm/gevm/go.mod:3: invalid go version '1.25.5':
    must match format 1.23

Pin the workflow to Go `stable` (with check-latest so we pick up new
1.25.x patch releases). Also bump `actions/checkout` and
`actions/setup-go` to v5 so the runner's deprecation warning about
Node 20 goes away (v5 ships on Node 24).

Drop the `git submodule update --init --recursive` from the test step:
.gitmodules declares fixture submodules but the tree contains no
gitlink pointers, so the command was a silent no-op. Fixture-gated
tests already self-skip when their env vars (GEVM_TESTS_DIR / etc.)
are unset, which they are on stock CI.
