Add a setting to configure display of auto detected links, normally and on hover

Description of the new feature/enhancement

Allow the user to define how detected patterns should be displayed, when hovered and not.

See (see #7691 (comment)) and this

Wanted to make this an official issue where we can discuss the extent to which this should be implemented (should it just be limited to font style? or also font face? and what about font size? or other effects too)

So, mixing and matching multiple fonts in the same TermControl might be Hard, so let's leave different font faces out of the question for now. I think different attributes seems reasonable, but how do we express that in the JSON?

How does a map of key-value pairs sound? Allowed keys are foreground, background and any of the ExtendedAttributes values

[zadjii-msft]

wait so then it's

"foreground": "red", // a 16-color table value
"background": "#0044ff", // an RGB value
"underlined": true // ?

We need to comport this with the configuration flags for specifying different fonts, suggested in ... some workitem that exists on this repo. I don't want to do this without doing that, and they should definitely look roughly the same in terms of user-facing options.

That would be #1790.
