Delete `gh-readonly-queue` branches

[BD103]

There are a slew of branches on the main repository prefixed with gh-readonly-queue. These branches appear to be left over from Github's merge queue bot. The newest of these branches is 8 months old, so I believe the bot is no longer creating these spare branches (or now deletes them afterward).

If these branches are no longer necessary, can they be deleted?

[BD103]

There are also many other stale branches that could also be deleted, but those are technically out of scope of this issue.

• apply-deferred
• stray-cargo
• create-pull-request/patch
• gh-pages (unused after Publish dev-docs with Github Pages artifacts (2nd attempt) #10892)
• debug-framecount

I've cleaned up the incidental "I made a branch on the main repo" branches now, but most of the gh-read-only-queue branches could not be deleted. I'm not sure why; I'll file a ticket with customer support.

Awesome! It's weird that you could not delete them. Did you try using Github on the web or through git?

Additionally, did gh-pages not let you delete it, or are you keeping it for another reason?

[alice-i-cecile]

On the web. I wasn't confident about gh-pages so I left it for now.

Support update:

Thank you for bringing this issue to our attention. I have escalated this to engineering to remove the lock from this branch and will let you know as soon as I have an update from them.

Customer support has come through for me: these are now deleted. Thanks!
