feat: add s2 static colors

[pfulton]

Description

Adds the Spectrum 2 static colors from Spectrum Tokens via manual definitions.

Specifically, the values defined here match (at the time of authorship) the Spectrum Tokens static color values here.

These are considered additive to the system and should not cause any visual differences.

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Maybe dumb Q, but should this be https://github.com/adobe/spectrum-tokens/blob/main/packages/tokens/src/color-palette.json#L6491

I'm not sure if that blob hash is main? Or if it's different? :)

Good call out. It's the SHA from this point in time on main over there. I figured that if we ever needed to trace back to where these came from, at least we'll have some marker since these aren't directly associated with a Spectrum Tokens release.
