Create a custom welcome sign for IMS Wannsee

[github-actions]

This is an example issue used to demo the GitHub Flow with an example that is more appealing than a standard hello world web app. As part of this exercise, we will

• add a welcome sign to the Octocat generator with the name of IMS Wannsee (allows to showcase our graphical diffing capabilities)
  
• change some html for changed text (demonstrate inline-edit functionality and suggested changes feature appealing to designers)
  
• change some Javascript to have changes in the program logic as well (and allows to run Javascript unit tests and demo peer code review) - e.g. to enable printing

The project is hooked to a multi stage deployment pipeline that will create a review environment for every single pull request and the ability to promote to staging and production. This allows us to show case GitHub Actions, our integration with CI/CD like Heroku and Azure Pipelines and branch protection rules with commit status checks.


Furthermore, the master branch will automatically push to the associated GitHub pages site, giving us an opportunity to explain what Jekyll and GitHub pages are.

Amazing ✨ issue ✨ , when creating the pull request could you also localize the language of the Get Started Button?
