Chunk test suite when running on Github Actions

To chunk your Pest tests so that each node runs a portion of the entire suite successfully, you can make use of the --filter option provided by Pest.

Here's how you can modify your GitHub Actions workflow to achieve this:

name: pest

on:
  push:
    branches:
      - main

jobs:
  test:
    name: Run tests
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
      matrix:
        ci_node_total: [4]
        ci_node_index: [0, 1, 2, 3]

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

      - name: Install dependencies
        run: composer install

      - name: Run tests
        run: ./vendor/bin/pest --filter "ci_node_index == ${{ matrix.ci_node_index }}" --parallel

With this configuration, each node will run a portion of the entire test suite based on its ci_node_index. The --filter option filters the tests based on the condition ci_node_index == ${{ matrix.ci_node_index }}, ensuring that each node only runs the relevant tests.

Make sure to update your workflow file with the above configuration and commit it to your repository.
