This changes the changelog grouping feature a bit: it evaluates the
groups in the order they are declared in the config file, but renders
them following their `order` attribute.
This allows to have better filters, for instance, you might want to have
dependabot commits in another section, which does not need a high
priority in the changelog output, but does when evaluating, as it might
share the words with other groups: in goreleaser's case, the `feat`
prefix.
Giving that Go's regex seems to don't allow negative look-aheads (which
would help in this particular case), this seems like a good quality of
life improvement.
