Add Atlassian Design System palette

Adds the Atlassian Design System (Atlaskit) primitive color palette,
sourced from the design-system/tokens artifacts. Includes 9 chromatic
hue families (red, orange, yellow, lime, green, teal, blue, purple,
magenta) plus a light-mode neutral ramp, each with 12 steps
(100-1000, with 250 and 850 sub-steps).
