The Parallels documentation is incomplete and should include an example

Problem to solve

The page at https://gitlab.com/gitlab-org/gitlab-runner/-/blob/main/docs/executors/parallels.md

does not contain enough information for someone to follow to get the executor setup.

Further details

Proposal

We should include a proper example on how to use the parallels executor, ideally with a macos VM.

Who can address the issue

Technical writing + GitLab runner team.
