dynamic markdown links in labels and hints

[link](href) gets turned into <a href="href">link</a>
this is ${what} gets turned into this is <span class="or-output" data-value="/path/to/what"><span>

To support this a [dynamic link](${what}), we could create the following output:

this is a <a class="or-output" data-value="/path/to/what" href="">dynamic link</a>

and then change the outputUpdate function to do something different if output is an anchor.

There are a lot of cool workflows that are just out of reach because of this limitation.

A functional but not-delightful alternative is to use a text control with appearance url and a calculate.

XLSForm:

type	name	label	appearance	calculation
text	url	Click to send to whatsapp	url	concat('https://wa.me/', ${phone}, '?text=', 'Hi')

Since this request has been open for a while, I'm just jumping in, in support of the idea and hopefully we get it soon :)
