fix(release-script): Add the generation of changelog for the release (#2333)

* chore(changelog): regen missing versions
* chore(validate-commit): Accepts type without scope
The spec specifies that the scope is optional therefore we should not
enforce their use on the CI. However it is still a recommended practice
and we will enforce them when merging PRs.
* fix(release-script): Added the generation of changelog for the release
