Environment variables defined in the container are not evaluatable

[mulle-nat]

System information

• Operating System: macOS

• Architecture: x86_64

• Docker version: Docker version 20.10.7, build f0df350

• Docker image used in act: catthehacker/ubuntu:act-20.04

• act version: 0.2.23

Expected behaviour

I expected to be able to use container defined environment variables in if: statements.

name: CI

on: [push]

env:
# ENV2: # undefined here, but defined in local container 

jobs:
  build:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ ubuntu-latest] # macos-latest,

    steps:
    - name: Dump Environment
      run:  env | sort

    - name: Test
      if: ${{ env.ENV2 }} 
      run:  echo Test

Actual behaviour

ENV2 value is ignored, unless defined in workflow file.

We don't inspect Docker image for envvars, they should be in /etc/environment
