AVD AIB StorageSense script not working

Hello team, please fix the DisableStorageSense.ps1 script by moving function "Set-RegKey" to the begining of this script. It is failing with following error.

azure-arm: Set-RegKey : The term 'Set-RegKey' is not recognized as the name of a cmdlet, function, script file, or operable

I will send a pull request with the fix.

Open DisableStorageSense.ps1 and inspect where the Set-RegKey function is defined relative to its first use. Move the function to the beginning of the script, then verify that the script no longer reports Set-RegKey as an unrecognized command.
