ci(primitives): transition to new css primitives
GitHub no longer distributes primitives in JSON format. Also, the names of the values (CSS variables) have changed. Most of the new names correspond 1-to-1 with one of the old names. Some colors have also changed slightly (e.g. `fg-default`), but otherwise remain mostly the same. See https://primer.style/foundations/primitives/migrating
