PHP 8.1: PHP looking for xdebug/pcov even when coverage set to none

[jrfnl]

Describe the bug
I'm not 100% sure the bug is in this package or in PHP core itself, but when running any PHP script after setting up PHP 8.1, a build will fail due to Xdebug/Pcov not being found.

Version

• I have checked releases, and the bug exists in the latest patch version of v1 or v2.
• v2
• v1

Runners

• GitHub Hosted
• Self Hosted

Operating systems
ubuntu-latest

PHP versions
PHP 8.1.

To Reproduce

  example:
    runs-on: ubuntu-latest
    name: "Example"

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Install PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: '8.1'
          coverage: none

      - name: Require dependencies
        run: composer require --dev --no-install php-parallel-lint/php-parallel-lint
    
      - name: Install Composer dependencies
        uses: "ramsey/composer-install@v1"

      - name: Run linting
        run: vendor/bin/parallel-lint . -e php --exclude vendor --exclude .git

Expected behavior
No errors from PHP itself.

Are you willing to submit a PR?
Willing yes, but wouldn't known where to even look at this point. I defer to your far more extensive knowledge of this action.
