Add "Assignee" to PR Context variables
Is your feature request related to a problem? Please describe. Currently context variables under PR does not have assignee option. This is a common piece in our development flow and would like to have some automation on it.
Describe the solution you'd like Adding that var, probably an easy addition.
Additional context

Thanks for the suggestion @akotek! I think this could have some benefit, but we'd like to understand your situation a little better. Can you describe the use case you're trying to accomplish? That would help us determine the best plan to implement something like this.
I would like to verify each new PR has assigned to 1 or more devs, i.e: assignees.size >0.
so basically add a rule to my CM flow to check that and request changes.
We use the assignee field for dev-metrics.
