Act: Inputs in env not parsed

[kenorb]

Steps to reproduce:

1. On the empty folder, create new repo: git init.
2. Create the following files:

action.yml

name: 'Test'
inputs:
  MyInput:
    description: 'My input'
runs:
  using: 'docker'
  image: 'Dockerfile'
  env:
    MYINPUT: ${{ inputs.MyInput }}

Dockerfile

FROM ubuntu
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

entrypoint.sh

#!/usr/bin/env bash

echo Input: $MYINPUT

.github/workflows/action.yml

name: Action
on: push
jobs:
  Test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: ./

Problem

The script doesn't print my input.

% act -j Test
[Action/Test]   🐳  docker run image=act-test:latest entrypoint=[] cmd=[]
| Input: ${{ inputs.MyInput }}

It prints ${{ inputs.MyInput }}, instead of the value of the variable.
