Run the command below so that you get all the `master` strings. We are
ignoring some of them explictly since they are rules, or upstream
changes.

```shell
rg --hidden 'master' -g '!faq/README.md' -g '!.vale/gitlab/DefaultBranch.yml' -g '!.vale/gitlab/InclusionCultural.yml' -g '!executors/kubernetes.md'
```

This commit assumuses that
https://gitlab.com/gitlab-org/charts/gitlab-runner is using `main` as a
default branch as well.
