feat(semantic-release): switch to `conventionalcommits` changelog

The `conventional-changelog-conventionalcommits` permits to easily
configure which commit types are rendered or not in the changelog and
releases.

* Dockerfile.semantic-release-gitlab: the module must be installed.

* release.config.js: switch to `conventionalcommits` and configure the
  commit `types`.
