Khroma and Elkjs were raising errors in the license checker:

• ElkJS because its license is EPL-2.0 and we've never had that case before.
  • Added to allowed licenses.
• Khroma is MIT but the NPM package is not up to date with regards to that info, and thus the license checker returns "unknown" when querying NPM.
  • Manually assigned the license.

Test plan

CI, in particular the license check action
