Rendering of documentation in Intellisense and hover inconsistent

[egamma]

Testing #2230

The rendering of the documentation in the hover and in Intellisense is inconsistent, different font, font size, font family, and color.
Suggest to align on the way the documentation is rendered in Intellisense. It looks nicer.

FYI @bgashler1

• Delayed hover
• Diagnostics hover
• Glyph hover
  • Debug breakpoint expressions colorisation
• URL click hover
• Suggest widget
• Parameter hints widget

Totally agree. Only code should be in a monospaced font. The way it's done in the second image is how we should do it.
