Describe the bug
The format check is not reusable for other repositories to call upon it as seen here.

To Reproduce
Run format check on any cFS related repository that calls nasa/cFS/.github/workflows/format-check.yml@main.

Expected behavior
Format check should run for all repositories.

Code snips
The error can be seen below:

error parsing called workflow
".github/workflows/format-check.yml"
-> "nasa/cFS/.github/workflows/format-check.yml@main" (source branch with sha:83c735e469e96537b289a50574781abe113c1230)
: workflow is not reusable as it is missing a `on.workflow_call` trigger

System observed on:
GitHub Actions

Additional context
To resolve this issue, add back workflow_call.
