Automate generic `v<MAJOR>` release creation

**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.
