Add a new job for creating a new release branch for each new release

[Robert-96]

Create a workflow job that automatically generates a new release branch containing the model-visualizer.min.css and model-visualizer.min.js files for each new tag. This process allows the model-editor and live-viewer projects to use a specific versions, by using these release branches as CDNs with jsDelivr.

Below are the commands required to create a release branch:

git checkout --orphan release-v<version-number> 
git rm --cached -r .
git add model-visualizer.min.css model-visualizer.min.js 
git push -u origin release-v<version-number>
