RichTextBlock hyperlinks do not work with touch on Windows 11

See original GitHub issue

Describe the bug

Tapping a Hyperlink present in RichTextBlock content does nothing on Windows 11.

Steps to reproduce the bug

Install the XAML Controls Gallery app
Open the XAML Controls Gallery app and navigate to the RichTextBlock sample. (Navigate to Text > RichTextBlock or use deep link xamlcontrolsgallery://item/RichTextBlock)
Click the hyperlinks link in the second sample. Observe the browser opens.
Tap the hyperlinks link in the second sample. Observe nothing happens.

Or create a blank app with one of the affected NuGet packages below.

From what I can tell, this is caused by CommonStyles/Hyperlink_themeresources.xaml#L23 <x:Boolean x:Key="HyperlinkUnderlineVisible">False</x:Boolean>. Setting this value to True resolves the problem. Interestingly, despite the name, HyperlinkUnderlineVisible does not seem to affect whether the hyperlink underline is visible. This problem affects WinUI 2 and WinUI 3 in the same way. It looks like HyperlinkUnderlineVisible was added in Windows 11, as it is present and set to True in the generic.xaml file for 10.0.22000.0.

In my opinion, just strike the HyperlinkUnderlineVisible line in the WinUI style, since a) it didn’t work anyway, and b) it would resolve this issue, which is a major usability concern.
