Title: use the original Changes content as a base for munging, rather than whatever is in the repo after release

This allows other AfterRelease plugins to copy the Changes file from the built
distribution back to the repo and commit it, before we add in the {{$NEXT}}
line here.

This lets us commit the Changes file at the release tag exactly how it appears in the shipped dist.
