Incorrect inclusion of a PR with a git tagged merge commit

[consideRatio]

I ended up observing a PR included in the changelog, even though it was part of the previous tagged release. To reproduce this, one can do...

github-activity --since v3.0.5 --target jupyterhub/action-k3s-helm

I would expect that PR 73 should not have been written out to the changelog.

A motivation to think of this as a bug is that the comparison we link to, will not include the changes part of the commit that was most recently tagged.
