Workflow level `env` does not work properly in all fields.

[timharris777]

Describe the bug
When using workflow level environment variables they do not work when I use them to substitute for jobs.build.name or jobs.build.runs-on. See workflow file below for example:

name: Testing workflow leve env vars
on:
  push:
    branches:
      - develop

env:
  aws_account: cfaittoolsnp
  environment: dev

jobs:
  build:
    name: Deploy|${{ env.aws_account }}
    runs-on: ${{ env.aws_account }}
    steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Init
      run: |
        echo ${{ env.aws_account }}

To Reproduce
Steps to reproduce the behavior:
1.- Run the workflow file above to receive the following error:
The workflow is not valid. .github/workflows/dev.yml (Line: 15, Col: 11): Unrecognized named-value: 'env'. Located at position 1 within expression: env.aws_account,.github/workflows/dev.yml (Line: 16, Col: 14): Unrecognized named-value: 'env'. Located at position 1 within expression: env.aws_account

Expected behavior
The expected behavior is that using the workflow file above the build.name would be Deploy|cfaittoolsnp and the build.runs-on would be cfaittoolsnp.

Runner Version and Platform

Running latest version of linux self-hosted runner.

OS of the machine running the runner? linux (ubuntu 18.04)

I'm just wondering if there is any update on this? :)

Unfortunately, no-- env can still not be used. However, I have found that I can use either of the following:

• runs-on: ${{ needs.init.outputs.tag }} -> You would need to export the tag for the runner as an output in a previous step.
• runs-on: ${{ github.event.inputs.tag }} -> You would need to provide an input for the runner tag via worfklow_dispatch.

I'm new to GitHub, hence GitHub workflows. But this is the exactly the first issue I have with workflow. I'd image this is causing troubles for many of us.
Does anyone know the best way to attract attentions from GitHub on this?

@leonardchu, give the first post a thumbs up. Github says that they monitor that. Other than that I'm not sure.

Same issue with env in job strategy:

name: Python package

on: [push, pull_request]

env:
  target_python_version: 3.8

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      max-parallel: 5
      matrix:
        python-version: [3.7, "${{env.target_python_version}}"]

    steps:
    - uses: actions/checkout@v1
    - name: Set up Python ${{ matrix.python-version }}
      uses: actions/setup-python@v2
      with:
        python-version: ${{ matrix.python-version }}
    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install tox tox-gh-actions
    - name: Test with tox
      run: tox
