[Feature Request]: -Category parameter should be case insensitive

[AndrewPla]

Changed the command to use the -Contains operator rather than using .contains.

Thank you! There are a few more places where I used Contains method for the category inside the EnableEntries functions. Could you modify them too?

e.g. in FileSystemRegistry

[AndrewPla]

I ran this to identify all of the files that use .contains

Get-ChildItem -Path .\ -Filter *.ps1 -Recurse | ForEach-Object {
    if (Select-String -Path $_.FullName -Pattern '\.contains' -Quiet) {
        code $_.FullName
    }
}

Now there is just one instance of .Contains, which is used in ApplicationRegistry.ps1 on. line 75, but it is fine here.
if (-not $item.Path.Contains('!')) {

I see some formatting changes which reminds me that we should force the formatting. I will unify them later.

Thank you for the fix. Looks good on the feature wise.
