ci: Cache tools/ with GitHub Actions (#1043)

jklaw90 · web-flow · commit da733e54778e · 2022-01-03T10:12:31.000-08:00
We run `go mod download` to populate `$GOPATH/pkg` with dependencies,
the contents of which are later cached.

We did not previously run this for the tools submodule,
so those dependencies were not getting cached.
