Add support for `Hyperlink` on Skia
Current behavior
Hyperlink in TextBlock is not supported on Skia targets. This is due to the fact that GetCharacterAt method is not supported.

Expected behavior
"Uno Platform" should display and work as hyperlink.
How to reproduce it (as minimally and precisely as possible)
- Launch the Uno.Gallry app on Skia.GTK
- Click on “HyperlinkButton” option from the list.
- Observe "Uno Platform" is not displaying as hyperlink and not working as hyperlink when clicking it.
Nuget Package: Uno.UI.Skia.Gtk
Affected platform(s): GTK (Linux)
IDE: Visual Studio 2019 (version: )
Hyperlink is working for HyperlinkButton, But issue is still present for Official documentation and due to that reopening the issue.

Still the hyperlink is not working for official Documentation

The issue is currently the fact that Hyperlink within TextBlock on Skia is not supported. Changed the title accordingly.

Looks like it's working now?
@sakshi173 Can you confirm?
The This paragraph contains an hyperlink that wraps over multiple lines, surrounded by regular text. one is probably missing an underline for part of the hyperlink.

@sakshi173 can you open an issue specifically for this?
@jeromelaban, sorry I didn't get it exactly, but now the issue is the link Official Documentation is missing for WASM and Skia.Gtk and I can raise a separate issue for that, please let me know your views.
@sakshi173 Actually, let's keep as is in this issue, after looking again at the issue.
This is now working!
