Improve Cypress Dashboard Support

[prescottprue]

There are a few things happening when using with Cypress Dashboard:

1. Commit message is not showing, instead a somewhat unclear of merge info is included even though no merge is going on (see picture below)
2. The branch name doesn't show at all (usually above the commit message)
3. The environment shows up as "Unknown". For Gitlab it shows "Gitlab feat: custom test command #123" the number being the build number. Maybe for this it could be a link to the action run? (see picture below)
4. Quitting a Github Action run while it is running test leaves the run in the dashboard in the "running" state (as if the dashboard was never notified about the cancel)

Not sure if this is the right code base for the changes, but wanted to get it reported

Let's wait until cypress-io/cypress#5687 is released in 3.7.0 it should fix 2 and 3. For 1 - this is pull request event right, so I am not sure what a beter name would be ;)
