Create `.github/workflows/build.yml` for running test suite

[yhouyang02]

THIS SHOULD REPLACE test.yml FROM THE TEMPLATE.

Your task here is to make sure the workflow in .github/workflows/build.yml is correctly configured so that at a minimum, it runs the test suite and style checkers on pushes and pull requests to your project’s repository’s deployment branch (typically the main branch). At time of submission, we expect that your project successfully runs this workflow.

A couple things you might need to change in your .github/workflows/build.yml file:

Ensure the deployment branch (typically the main branch) is correctly specified on lines 7 & 10

Ensure that the correct Python version is listed on lines 21 and 24 (it should match the version in your pyproject.toml file)
