Now workflow calls can be nested

[rhysd]

https://github.blog/changelog/2022-08-22-github-actions-improvements-to-reusable-workflows-2/

You can now nest up to 4 levels of reusable workflows giving you greater flexibility and better code reuse.

At least the following workflow should not cause an error.

on:
  workflow_call:
    inputs:
      message:
        description: additional message
        required: true
        type: string

jobs:
  call-another-workflow:
    uses: ./.github/workflows/another-workflow.yaml
    with:
      hello: ${{ inputs.message }}

actionlint currently reports an error as follows:

test.yaml:11:11: reusable workflow cannot be nested. but this workflow hooks "workflow_call" event at line:2,col:3 [workflow-call]
   |
11 |     uses: ./.github/workflows/another-workflow.yaml
   |           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

4 levels of reusable

I don't think actionlint can check levels statically (e.g. recursive call using if:).

This was fixed in v1.6.17.
