Go: remove language tests from workflows

Now that they are run internally using QLucie.

Mostly just a question about this: why does go-tests.yml survive with a pull_request trigger, but go-tests-other-os.yml does not?

Linux was using the testing action with run-code-checks: true, so it was not just running language tests. The other-os and rtjo workflows weren't passing that option, which means they were only running language tests, which made those workflows entirely redundant with the internal tests.

To make this clearer we can probably remove the run-code-checks parameter, now that it is always true.

In any case, I think it's good to wait a bit with this to let the dust settle on the internal tests, like you mentioned on the internal PR.
