Comment Spacing, Indentation, and Capitalization (#1084)

* Comment Spacing, Indentation, and Capitalization

* Comment Grammar and Spacing

Makes grammar in comments better and more consistent
Adds space before comment and centers word in `Write-Host` commands

* More Grammar and Formatting

* Add some comments

* Populate PlaceHolder comments in functions

Files I found that has issues:
Get-WinUtilRegistry.ps1
Install-WinUtilWinget.ps1
Invoke-WinUtilDarkMode.ps1
Remove-WinUtilAPPX.ps1
Test-WinUtilPackageManager.ps1
Update-WinUtilProgramWinget.ps1

Invoke-WPFUpdatessecurity.ps1

* Tweak a few more comments

* Tweak another write-host statement

* Undo Catch statement adjustment
