1.3.0

The highlight of this release is the official "induction" of "[email protected]"
as a valid base/build-base, no longer requiring the "devel" build-base.

Of note, the [email protected] base changes the rock's entrypoint to no longer have
"--verbose" by default. There are other "big" changes in this version but they
are mostly internal refactorings and updates. We have actually "inherited" a
couple of features from craft-application (like adopt-info and grammar), but
these should be considered "experimental" from Rockcraft's point of view because
we haven't had a chance to exercise those features in the project yet.

Special thanks to the contributors that made this release happen: @jdkandersson, @linostar, @renovate, @renovate[bot], @tigarmo and @weiiwang01
