Documentation: Describe how to label if _any_ file in the repository has changed or to _every_ PR

[ejether]

Description:
I'm using Labeler to add a default label to every opened PR. I've been unable to devise a set of globs that have reliably done what I needed. I've tried a handful of things that did work sometimes but not on every pr.

norelease:
  - any: [ '**/*','.*/*','*' ]

norelease:
  - './**/*'
  - './.*/*'
  - './*'

norelease:
  - '**/*'
  - '.*/*'
  - '*'

I'd like to know what to do to label every pr with a label

Justification:
I'm using the action to put a default label on every PR that affect downstream actions. The user could add the label manually and that's the work around but since in this repository, the label is always the same, I'd like to have it JustWork™ for my team.

Are you willing to submit a PR?
Sure, if it comes to that
