feat(icons): Add question-mark icon

[jamiemlaw]

Partially addresses issues #1858 and #119

Description

Adds a question-mark icon, without any surrounding circle.

Icon use case

This has overlapping use cases with circle-question-mark, with the major exception that it allows the user to surround it with their own shape, e.g.

• A help button
• Hints in puzzle games

feels a bit small to me

You're not wrong. I matched it to the size of italic, bold, ligature and type—other text symbols. I could look to increase it though.

A few sizes larger. My favourite is the first, then the third, then second; the proportions of that one look off to me.
