Command used with act

act pull_request -P self-hosted=ubuntu --job debug-gh-action

Describe issue

The strategy context is missing job information, and doesn't comply with github actions contexts reference

act's strategy object is :

{
  fail-fast: true,
  max-parallel: 4
}

Instead of something like :

{
  "fail-fast": true,
  "job-index": 3,
  "job-total": 4,
  "max-parallel": 4
}
