Review @primer/octicons-react usage, update/replace dependency

[fregante]

Our @primer/octicons-react package cannot be updated:

• v17.11 breaks dom-chef
• v19 uses forwardRef

There were a couple of attempts at fixing this:

• Meta: Replace dom-chef with jsx-dom  #4044
• A brief investigation of using SolidJS #6493
• Use Preact? #4058

Probably jsx-dom is the best transition we can do right now, but also it's probably not working with v19.

So I think the easiest way forward would be to:

1. import the raw SVG
2. have webpack turn it into JSX-compatible imports ("svgr")

This should be reasonably easy to implement and likely the most stable and lightweight solution (octicons-react has more code than we need, at this point)

This issue is made super visible by visit-tag (due to lacking of https://github.com//primer/octicons/pull/858)

Yeah let's restore SVGR soon so we'll skip all the React drama. I think the npm package still includes the SVG:

(That file is handled by parcel so the syntax isn't the same)
