You may have pressed the button, but the actual commit action was done by GitHub's infrastructure, hence they are listed as committer. Think of it as an acknowledgment that maybe they were hacked and made to do the commit even if you didn't want it.
If you want to do the commit yourself, you can run `git merge` locally and push the result. They won't touch the commit (including the committer) in that case, because the commit hash must never change. I'm not sure if they track who did the push (or even what the sensible value would be if two people pushed the same commit to two different forks).
