Open questions

• There no precedence for including naming of color and monochromatic versions of the same icon. I went with Alt for the monochromatic one, but I'm unsure if this is the optimal approach. I'd like an opinions of what seems like the most sensible naming for these icons if you got them.

@dancormier I think using Alt is fine. This will likely only ever get used in the footer and maybe some other legal page or something.

@abovedave Any preference or thoughts?

I am not sure if I fully understand the purpose of the icon filled with blu here.

If the goal is to get the svg to inherit the color of the parent element's background then we should probably stick with one icon supporting current color like we do in the Stacks Logos repo (see PR).

I took the liberty to make a commit in this PR that introduces the same mechanism @abovedave introduced in Stacks Logos to easily highlight the fill="currentColor" part of an SVG (that should be easily revertible if we decide to do something different).

We need a designer now to help us out adjust the icon in Figma accordingly to use currentcolor. @CGuindon @abovedave perhaps you could sync and double check if we can use here the same approach we use in Stacks Logos. Thank you. 😊
