Treating warnings as erros issue during github build

By default github treats warning as errors and fails during build. For our projects let us ignore it with env: CI environment variable

name: Deploy to Firebase Hosting on PR
env:
  CI: false
'on': pull_request
jobs:
  build_and_preview:
    if: '${{ github.event.pull_request.head.repo.full_name == github.repository }}'
