`X-Needs-Percy` label does not seem to run on the merge queue

[luixxiul]

Steps to reproduce

1. Create a PR on https://github.com/matrix-org/matrix-react-sdk (such as https://github.com/matrix-org/matrix-react-sdk/pull/10744)
2. Add X-Needs-Percy label to the PR
3. Add the PR to the merge queue

Outcome

What did you expect?

Percy should run for the PR, according to the documentation: https://github.com/matrix-org/matrix-react-sdk/blob/develop/docs/cypress.md#screenshot-testing-with-percy:

If your pull request makes visual changes, you are encouraged to request Percy to run by adding the label X-Needs-Percy to the PR, these will only run in the merge queue to save snapshots.

What happened instead?

It seems it did not run: https://github.com/matrix-org/matrix-react-sdk/pull/10744#event-9143888691

I think this line should be github.event.workflow_run.event == 'merge_group'. merge_queue is not listed at https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows.

@richvdh that seems sane, I made that mistake many times, my brain seems to refuse to accept that github didn't name them the same damn thing
