Actions are not recognized when in parallel steps.

**Describe the bug**
Actions used in steps that use the parallel shorthand are not recognized by the extension and do not appear with information about the action.

**To Reproduce**
Steps to reproduce the behavior:
1. In a job, create a step that uses the parallel keyword.
2. Attempt to use at least one action in a step.
3. Observe the missing action details.

**Expected behavior**
Similarly to normal steps, actions in parallel steps are recognized and are ctrl+clickable & have information that is viewable on hover.

**Screenshots**
Parallel action (notice there is no underline):

Normal action (also shows information about the action on hover):

**Extension Version**
`v0.32.1`

Start by reproducing the issue with a GitHub Actions job using the parallel shorthand, then compare action recognition in parallel and normal steps. Trace the extension's action-link and hover-information paths; done means actions in parallel steps are recognized, ctrl+clickable, and show information on hover like normal steps.
