`github.action_repository` and `github.action_ref` are empty in `run` for composite actions

Describe the bug
github.action_repository and github.action_ref are empty in run for composite actions

To Reproduce

1. Set up a workflow that uses an action that uses github.action_repository / github.action_ref in run in a step.
2. Trigger a run for the workflow

Expected behavior
github.action_repository / github.action_ref should be filled in for run just as it is for env

Runner Version and Platform

Version of your runner?
Current runner version: '2.302.1'

OS of the machine running the runner? ubuntu-latest

What's not working?

github.action_repository / github.action_ref are empty

Runner and Worker's Diagnostic Logs

If applicable, add relevant diagnostic log information. Logs are located in the runner's _diag folder. The runner logs are prefixed with Runner_ and the worker logs are prefixed with Worker_. Each job run correlates to a worker log. All sensitive information should already be masked out, but please double-check before pasting here.

Reproduce the workflow with a composite action that reads github.action_repository and github.action_ref in a run step, using the linked job log as the reference case. Compare those values with their behavior in env, then trace the runner's composite-action context handling. Done means both variables are populated in run steps as expected and coverage verifies the behavior.
