Enhancement | Add release + notes at GH repo and auto-sync readme (if possible) in DockerHub

Describe the Enhancement

Add a way to create releases and release notes in the repo and add/update a readme in Docker Hub.

Expected Behavior

To have up-to-date notes.

If possible keep the standard approach and format that's being used across all binbash GH org repos => https://github.com/binbashar/leverage/releases with https://github.com/binbashar/leverage/blob/master/.github/release-drafter.yml

Use Case

When a user wants to know what changes we have in a release, it should be a release page with all the details.

Describe Ideal Solution

Now the workflow is:

build an image
create a tag

The ideal workflow should be:

create a PR
merge it to master
do the same with all the PRs you need
then release drafter will create the draft for all the PRs
publish the release
the previous action triggers the image build/push with the desired version

Keep in mind we have to figure out how to maintain two different image versions (aka two different releases). This can be done with version branches. E.g. for versions 1.2.7-0.1.1 and 1.3.5-0.0.1, being the later the main one:

from master we build the latter one
from release/1.2.7 we build the former one

Another possibility is not to work with master and instead have all release branches and work from there:

release/1.2.7
release/1.3.5

I don't know how release drafter works, so it has to be researched.
