📚 Decide and Document a longterm support strategy #328

As user and developer of the secureCodeBox I would like know the support strategy for this project.
This strategy should include:

• the number of versions currently supported
• EOL date for each version

At this Point there is no offical support timeline for a release.
We currently release about every two weeks dropping support for the previous version.

The strategy will be published in the GitHub repository as well as in the documentation of the secureCodeBox
