[lang] yaml 1.1 vs yaml 1.2 support

[Naatan]

My yaml source contains:

on:
  push:
    branches:
      - master
  pull_request:
    - master

Which gets compiled as:

true:
  push:
    branches:
    - master
  pull_request:
  - master

currently ytt uses yaml library that follows yaml 1.1 spec i believe. in that spec on is equivalent to true. to make this work youll have to do something like this:

"on":
  push:
    branches:
      - master
  pull_request:
    - master

btw give --strict a try for this case. it's puts ytt into mode where it checks against yaml ambiguities: https://github.com/k14s/ytt/blob/develop/docs/strict.md

Thanks for the workaround! That unblocks me for now at least :)

#407 outlines an approach to solve this.

Ideally, the older issue remains and the younger issue is closed as a duplicate. In this case, progress has been recorded on #407, so closing this issue as a duplicate.
