adds info about required pull-requests permission

[jritsema]

I needed to add the pull-requests: true permission in order to get this to work.

Sorry for the delay, I'll look to incorporate. Thanks for the PR!

Looks great. Thanks!

@jritsema I added the permissions to the workflow on master and merged in, but Dogfood is still failing. Does it look like I did that right?

Trying to figure out permissions. It just seems like they are for using more granular permissions on your jobs. Adding to the docs makes sense so that people know what is required. I think the perms required are actually these:

    permissions:
      issues: write
      pull-requests: read

Can you update the PR with those if that makes sense?

Working with it a bit more, I see pull-requests: write is definitely required and issues is not. Very weird, since the methods used are all issues scoped.
