Add-HTMLStyle -Link broken in many versions

I've used Add-HTMLStyle -Link <link> -Placement <header|footer> in a number scripts over the years and not sure how i missed that it was never working. Generally the CSS I was adding was overkill so likely not noticeable.

Issue

It appears that this was first introduced in commit 1d42199 Where the <style> tag is added to anything going to the header or footer.

When using Add-HTMLStyle to add a CSS link to <head> or <footer> the end result looks like this:

<style>
    <link rel="stylesheet preload prefetch" type="text/css" href="https://unpkg.com/tabulator-tables@5.5.0/dist/css/tabulator.min.css" as="style"/>
</style>

Example code to reproduce

Add-HTMLStyle -Placement Header -Link 'https://unpkg.com/tabulator-tables@5.5.0/dist/css/tabulator.min.css'

Note: -Placement Inline is not affected by this due to the code here: https://github.com/EvotecIT/PSWriteHTML/blob/master/Public/Add-HTMLStyle.ps1#L87-L93

Possible Fix - modify `Private\New-HTMLCustomCSS.ps1`

I've modified the New-HTMLCustomCSS function with the below code in my $home\Documents\PowerShell\Modules\PSWriteHTML\1.1.0\PSWriteHTML.psm1 and ran various tests. All appear to work without issue.

function New-HTMLCustomCSS {
    [CmdletBinding()]
    param(
        [System.Collections.IDictionary] $CSS,
        [switch] $AddComment
    )

    $Output = foreach ($Key in $CSS.Keys) {
        if ($AddComment) {
            "<!-- CSS $Key AUTOGENERATED on DEMAND START -->" 
        }
        if ($CSS[$Key]) {
            #if ($CSS[$Key] -notlike "*<style *") {

            $CSS[$Key]

            #} else {
            #    $CSS[$Key]
            #}
        }
        if ($AddComment) {
            "<!-- CSS $Key AUTOGENERATED on DEMAND END -->" 
        }
    }
    if ($Output) {
        $Output.Where({ $_ -like '<!-- CSS * START -->' })
        New-HTMLTag -Tag 'style' -Attributes @{ type = 'text/css' } {
            # $Output
            $Output.Where({$_ -notlike '<link *' -and $_ -notlike '<!-- CSS*'})
        } -NewLine
        $Output.Where({ $_ -like '<link *' })
        $Output.Where({ $_ -like '<!-- CSS * END -->' })
        # notate where this may impact other areas via html output.
        '<!-- MONKEYPATCHED_New-HTMLCustomCSS -->'
    }
}

Some noteworthy successful tests are:

[x] testing with multiple lines of Add-HTLMStyle
[x] using -Link and -Content
[x] above tests along with -AddComment switch

Untested:

[ ] -Css
[ ] -FilePath
