v7.4.0 of the Octicons release added support for React components, and v8.0.0 introduced a breaking change to use the @github/octicons-react package name instead.

This is of interest to me because the generated octicons.generated.ts contains the entire set of icons:

And it makes up a significant part of the generated renderer bundle:

My gut feeling is that webpack isn't stripping out the unused source in the app (because of how the OcticonSymbol class is structured) and if we move to using the @github/octicons-react package we'd get the benefits of tree-shaking (because it's able to analyze which symbols are actually used in the app) as well as eliminating some boilerplate code for generating the OcticonSymbol class.

I'm not going to mark this as help wanted just yet, because it's used rather heavily across the codebase, and there are no typings available for it yet.
