fix: add Documentation and Dependencies to release notes (#1014)

Generate release notes with `Documentation` section from commits
prefixed with `docs:` and `Dependencies` from commits tagged with
`deps:` and `deps(dev):`.

Configure dependabot to add the `deps:` and `deps(dev):` prefixes.

Interested projects should run `npx aegir check-project` to get the
updated config.
