Bug/3979/web demo version

[BenediktMehl]

Web demo gets reset to Version 1.132.1

Closes: #3979

Description

Every time the "Deploy to GitHub Pages" workflow got triggered the web demo was reset, because the deployment uses the gh-folder as source. The web demo build in that folder is never updated, because the release-visualization.yml directly deploys the release artifacts to the gh-pages branch.

Solution is just deleting the visualization folder inside the gh-pages folder on main, so the visualization folder on the gh-pages branch is no touched by the deploy-github-pages workfow.

Also I changed that all the time a clean deployment is dont because else there are very old and unused files on the gh-pages branch.
