remove trailing comma when generating enums

[graphicsxp]

Hey,

I'm not very familiar with the templating tool used by the breeze generator, but how would you remove the trailing comma ?

{{#each values}} {{this}} = {{lookup ../ordinals @index}},

generates

export enum ProductColor { Red = 0, Green = 1, Blue = 2, Yellow = 4, }

if the last enum value is followed by a comma, this gives a linting error so it's a bit annoying when generating metadata...
