Actionlint complains "with" section is alias node but mapping node is expected [syntax-check] on valid YAML syntax when anchors and aliases are used with mapping nodes:

- name: Run my-action.
  run: my-organization/my-action
  with: &my-action-inputs
    a: b
    c: d
    e: f
- name: Run my-action again.
  run: my-organization/my-action
  with: *my-action-inputs

I am uncertain how one would suppress the error.
