Please add support for <paramref> tags

[azurefx]

Hello, I encountered a problem when generating documentations with <paramref> tags.

Currently xmldoc2md treats these tags as "regular" tags and takes innerText instead of the name attribute. This means that if there is such a comment:

// <summary>
/// See parameter <paramref name="myParam"/>.
/// </summary>

Then the generated document looks like this:

See parameter .

The relevant code looks like here:

Maybe adding a switch case will solve this problem?
