Does not skip duplicate runs after a merge_group trigger

[haugene]

We're seeing consistent duplicate runs when the first run was done as part of a merge_group. The skip-duplicate action is outputting: Do not skip execution because we did not find a transferable run even if the exact same commit hash have already succeeded as part of a group and is now merged to main in our repo.

I suspect that the workflow filter implemented here is causing duplicate runs to pass the check when the first run was executed as part of a merge_group.

if (run.id !== currentRun.id && run.head_commit) {

The GitHub trigger docs show that a merge_group trigger does not have a head_commit but instead has a merge_group.head_commit.

I'm not too familiar with TypeScript and how fields are mapped here. But could we add another check here to include runs that have merge_group.head_commit present?
