Workflow Dispatch checkout merge commit from forked branch.

[davinchia]

Hi,

First, apologies if this is not in the right spot. I saw the issue comment and my question is related to checkouts so I think this is the right place.

We currently use the workflow dispatch event with the checkout action to start integration tests on PRs. This is working beautifully on the main OSS repo but not too well with forked repos. Specifically, I'm wondering if there is a way to configure the checkout action to checkout the merge commit from a forked repo, similar to how the pull request event has it. I can't seem to find this in docs and google isn't giving me great results.

Thanks.
