• Did you read and follow the Atlas Contribution Guidelines?

Describe your pull request

• Adds an 'indexConf.cmd' script that can toggle search indexing, add paths to it, and exclude paths from it
• Doesn't disable search indexing by default but instead makes it minimal by excluding the 'Users' folder
  • This makes it so there's little to no CPU usage after initial indexing
  • This is in the form of a 'Minimal Search Indexing (default).cmd' script
• Adds 'AtlasDesktop' to search indexing so that users can search for scripts in their start menu
• Makes the 'Enable search indexing' script reset to the default search indexing settings, except AtlasDesktop

This is in response to the following features requiring indexing: web search on Windows 11, slideshow lock screen, and kDrive.

From my testing on Windows 11 with these scripts, everything seems to work, but I want to ensure it's all good, so testing on a VM (while checking the indexing settings to ensure it all works) would be appreciated.
