chore (workflows): Don't use redundant action

This action has multiple flaws:

* It is redundant, since we execute `make lint` in
`.github/workflows/ci.yml`.
* It ignores `make lint`: If we want to remove our build artefacts from
the repository, then we can't run `golangci-lint` without first creating
the artefacts.
* It contains redundant logic.
