fix: keep path to event json file in composite actions

[KnisterPeter]

The event.json paths need to be copied over, since it the
GithubContext is recreated from the composite RC. And that
does read some value from the event file if available.

Fixes #1401

Add this test? You can append the steps to the test for github.head_ref github.base_ref

on: push
jobs:
  _:
    runs-on: self-hosted
    container: ubuntu:latest
    steps:
    - run: |
        runs:
          using: composite
          steps:
          - run: |
              echo WORKFLOW_GITHUB_CONTEXT="$WORKFLOW_GITHUB_CONTEXT"
              echo COMPOSITE_GITHUB_CONTEXT="$COMPOSITE_GITHUB_CONTEXT"
              [[ "$WORKFLOW_GITHUB_CONTEXT" = "$COMPOSITE_GITHUB_CONTEXT" ]]
            env:
              WORKFLOW_GITHUB_CONTEXT: ${{ tojson(tojson(github.event)) }}
              COMPOSITE_GITHUB_CONTEXT: ${{ '${{tojson(github.event)}}' }}
            shell: bash
      shell: cp {0} action.yml
    - uses: ./

I verified that this change fixes the issue and this test will only pass with a user provided event.json file with this patch.

• WORKFLOW_GITHUB_CONTEXT is hardcoded into the action and has the value of the workflow level github.event.
• COMPOSITE_GITHUB_CONTEXT is evaluated inside the action

Both should be equal.

I prefer that this includes a test, like the one in my comment. However this should be fixed asap.

[KnisterPeter]

You are right that we need a test for this. It's quite important.

The test from above doesn't seem to work as expected.

[ChristopherHX]

Copy pasting a test is not trivial, I will fix your yaml errors

Thanks 😂
