Powershell Script to uninstall Solr Service and delete Solr instance folder

This script is useful uninstalling Solr when you have multiple  instances of Solr running from different folders in the same machine. In other words, this script does a reverse of https://navansitecorenotes.blogspot.com/2020/06/ps-script-changes-to-run-multiple.html wherein Solr gets installed in a folder specific for that instance. So, use this powershell script  only if your solr is running from a specific folder since it deletes the concerned folder and also the Solr service.
