7046: Update to the 2021-03 platform

[thegreystone]

Also updating to latest babel for the platform versions that are available in 0.18.3.

Depending on if #234 gets in before or after this one, either this one will need to be updated to remove the chromium entry, or #234 will need to be updated to do it.

(Is it just me, or does JMC start really fast on 4.19? :) )
