Added instructions for running scripts under windows if they are typically not allowed. This is not that hard to find out and maybe is just bloating up the README file unnecessarily.

+# Problem running scripts on Windows with Powershell
+
+In case you are having issues with running scripts under Windows,
+you can set the execution policy with
+[`Set-ExecutionPolicy`](https://docs.microsoft.com/de-de/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-7.1).
+If using the RemoteSigned execution policy, you can use `Unblock-File`
+to allow specific scripts to run.
