Release notes come from app-stores' changelog action, into the deb and rpm too

The release's "What's new" is now written by the shared generator every Arasaka
release uses, from the same commit messages and with the same "me-web? x.y.z:" prefix
removed; the deb and rpm carry it as their changelog (apt changelog, rpm --changelog),
and CHANGELOG.md is attached beside the files and listed in SHA256SUMS.txt.
