Reset Powershell environment

We need to reset Powershell environment since it is inherited from the runner process.
For that, we use the chocolatey helper script that needs to be imported
and called.
We also make sure that JAVA_HOME is set properly to the one set up by the setup-java action
and other predefined Registry values do not interfere.
