Create a generic `v<MAJOR>` release

Is your feature request related to a problem? Please describe.
Right now we are not releasing a vMAJOR tag/release pointing to the lastest version of the MAJOR stream.

The drawback of this approach is that, users MUST have to update the minor/patch version every time.

Describe the solution you'd like
For every release (either minor or patch), release an additional vMAJOR release pointing to the latest version.

Example
If we release v4.7.0, also release v4 pointing to the v4.7.0.
If v4 already exists, simply overwrite it with a new one such that it will always point to the latest.

Describe alternatives you've considered

Temporarily creating manual tag and release (for v4) every time a new release is out, e.g., https://github.com/kiegroup/git-backporting/releases/tag/v4
