Test failure introduced by #175

[AJFSalomon]

I updated my own plugin project with the timeout change in test_and_deploy.yml introduced in #175, and it caused the following test failure after git push:

Invalid workflow file: .github/workflows/test_and_deploy.yml#L23
The workflow is not valid. .github/workflows/test_and_deploy.yml (Line: 23, Col: 5): Unexpected value 'timeout'

I was able to replicate the bug twice by creating brand new plugin templates with slightly different parameters.

I fixed the bug in my own project by replacing timeout: 30 with timeout-minutes: 30. I will file a PR for this, but I figured it was good to also file an issue since the cookiecutter test procedure did not catch the problem.
