Issue

Powershell 7 scripts do not run in native workers via run: step, and report a false positive of succeeding

Steps to Reproduce

With the following simple config:

name: Test
on:
  push:
  pull_request:
    branches:
      - main

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - shell: pwsh
        run: |
          "this should work!"
          "Evidence" > /github/workspace/worked

and swapping in the official powershell worker (and using -r so the container doesn't disappear):
act -rvP ubuntu-latest=mcr.microsoft.com/powershell:lts-ubuntu-18.04
The result says success:

However upon inspecting the image via attaching a shell to the docker container the "evidence" file was not created:

And running the command manually in the container from shell shows an exec problem

Running the command using the -f format works fine however

I confirm that this is not working currently. I encountered this issue with a similar flow.

I use karolczajkowski/dotnet-ubuntu-dind image with pre-installed pwsh. Same thing happens whenever I run steps which use the shell token.

After extensive debugging I found the issue, when the command is built, the space splitting in the array does not split it correctly, the powershell command should all be on one line

I'll fix this in the PR, this is also why the -f method worked
