Fix autograding to divide points

[sgbaird]

Existing example from https://github.com/ACC-Robotics/1-pumps-and-pipettes/blob/main/.github/classroom/autograding.json

{
    "tests": [
      {
        "name": "Run pytest",
        "setup": "pip install -r requirements.txt",
        "run": "pytest",
        "input": "",
        "output": "",
        "comparison": "included",
        "timeout": 10,
        "points": 100
      }
    ]
  }

Use pytest file_name.py::function_name syntax to assign partial points (and make sure points add up to the total for the assignment, 10 points in most cases).

This is the new yaml syntax, which we should try to switch to: https://github.com/ACC-Robotics/0.2-intro-github-classroom/blob/main/.github/workflows/classroom.yml

E.g.,

name: Autograding Tests
'on':
- push
- repository_dispatch
permissions:
  checks: write
  actions: read
  contents: read
jobs:
  run-autograding-tests:
    runs-on: ubuntu-latest
    if: github.actor != 'github-classroom[bot]'
    steps:
    - name: Checkout code
      uses: actions/checkout@v4
    - name: Hello world test
      id: hello-world-test
      uses: classroom-resources/autograding-python-grader@v1
      with:
        timeout: 5
        max-score: 5
        setup-command: sudo -H pip3 install pytest
    - name: Autograding Reporter
      uses: classroom-resources/autograding-grading-reporter@v1
      env:
        HELLO-WORLD-TEST_RESULTS: "${{steps.hello-world-test.outputs.result}}"
      with:
        runners: hello-world-test
