Create release Workflow

[offtherailz]

Description

the release workflow creates a release on MapStore, builds the proper artifacts and upload them.
This speeds up the release process and do not need jenkins.

TODO:

• The only thing missing is the docker publishing.

From Github UI one run it :

@randomorder we have this PR still in draft that would allow effectively to replace the release Jenkins job with a github action and make the workflow smoother. It is only missing of the docker publishing. A review/feedback from you would be great. Could we maybe integrate the docker part here?
