Adding some information on the Workflow Run trigger

[gs-emp]

Adding information about when the workflow_run triggers - this should be helpful for people who don't know it will only run in the default branch

[int128]

Sorry, does it mean the following considerations?

• A workflow of workflow_run is triggered for any event by default.
• A workflow of workflow_run is evaluated in the default branch. For changing the options of this action, we need to change the default branch.

Mainly that the workflow_run trigger is only evaluated from the default branch. You can specify what branches and such.

I think for people when they add it to their repo may be confused by the fact that it won't trigger in a pullrequest or in a different branch.

So for example:

• I add this in my feature/datadog-metrics branch for repo X
• I make a pull request and am not sure why the trigger is not happening.

Not sure if my wording in the pr is great let me know at @int128

Gonna close this as we aren't using this anymore and clearing up my repos
