fixup! Add a GitHub workflow to monitor component updates

We've switched from p7zip to regular 7-Zip recently[1][2][3].
With that we don't need to monitor p7zip for updates anymore, but
we want to stay informed about 7-Zip updates now. Change the feed
accordingly. Since the new feed contains 15 different files as
separate items for the latest 7-Zip update, aggregate them into a
single issue.

[1] git-for-windows/build-extra#526
[2] git-for-windows/build-extra#527
[3] git-for-windows/build-extra#530
