crash when clicking on an empty link

[vpenades]

A markdown like declared like this:

[Empty Link]()

Is displayed correctly, but when clicked, it crashes with this exception:

System.InvalidOperationException: 'Cannot start process because a file name has not been provided.'

Avalonia: 11.2.0
Markdown.Avalonia.Tight: 11.0.2

You should probably update the description with the Avalonia version and the Markdown.Avalonia version.

I've updated the issue.

Additional context:

Given that an application may open markdown files from unknown sources and potentially malformed or incomplete, it would be expected that clicking on a link with an empty URL results in no action performed instead of throwing an exception.
