Currently the neo datetime datagen uses the v1 data structs in order to generate v2 data structs. This was a shortest-path solution at the time to get neo up and off the ground, but now it is tech debt, and we should rewrite v2 datagen to read directly from CLDR-JSON data structs.

Also, make sure the word "name" refers to a localized string and "symbol" refers to the placeholder string. #4328
