I triggered the documentation update automation to test the workflow, and it automatically created this PR.
It’s no longer needed, so it can be closed.

@ConnorLand - are you aware of this? Perhaps you can discuss how this might work in the future in terms of our processes (and the CLA signing)?
Thanks.
