cfpb-icons: Add numerical icons

[anselmbradford]

We had numerical icons in the source svg folder, but hadn't included them in the DS docs for some reason.

Additions

• Add numerical icons to the docs.

Testing

1. The PR preview iconography page should include icons.

I think the historical reason for this is that we put CSS in place to replicate them. There may have also been a licensing concern about the numerals being sourced from Avenir Next.

Thanks @Scotchester ! I'm holding the PR till we verify the licensing.

I recommend moving forward with the PR if this is time-sensitive or blocking other work. I'm still waiting to hear back from the licensing rep, but I don't anticipate there being an issue.
