fix: Fixing grid colors and grays (#1621)

- Styleguide didn't have 850 actually mapped.
- dh-gray-100 is mapped to content-bg but doesn't have a Bootstrap
gray-xxx counterpart, so I added a Gray-8XX for illustration while we
are still mapping things
- Grid row was mapped to dh-gray-200 but should have been dh-gray-300
- I added calculations for the hsl for grays instead of the all zero hue
based ones I had before. They are still not exact but closer. I'm
looking into fixing the rounding error.
