CLA bot is failing on new `merge queue` feature

[shazron]

Github merge queue: Adobe CLA check is stuck. Any ideas to get it unstuck? It probably can't recognize this new workflow (which at least for us will help with all the Dependabot PRs) and errors out.

1. https://github.blog/changelog/2023-02-08-pull-request-merge-queue-public-beta/
2. https://github.com/adobe/aio-cli/queue/master (click on any of the paper icons next to a queue entry) - If you don't see anything in the queue later today, it's because it was removed for no response from a check

Trying to read the cla-bot code - it appears that the bot probably threw an exception that was not handled, my guess is it's an undefined var at https://github.com/adobe/cla-bot/blob/602108f954f90edae74e8caa38cd12744b60c55a/checker/checker.js#LL36C47-L36C47

Does anyone at the OSO have access to the runtime logs, or are they forwarded to Splunk? https://github.com/adobe/cla-bot/blob/master/checker/checker.js

I believe the event is merge_group so will need to test for that instead of pull_request: https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-a-merge-queue

merge_group params are different from pull_request: https://docs.github.com/en/webhooks-and-events/webhooks/webhook-events-and-payloads#merge_group
