Generate version map for Plugin wikis

Make sure to also link to the Wiki table from your README.md files, e.g.:

    This branch is for use with **CakePHP 5.0+**. For details see [version map](https://github.com/repo-url/wiki#cakephp-version-map).
    

Note: This tool will read out the branches and based on those build the table. It currently does not yet support version rows without a branch.
Examples: [IdeHelper] | [DebugKit]
