Prevent the following workflows when a PR contains changes that affect
only the frontend:
 - Charmed Katib
 - E2E Test with darts-cnn-cifar10
 - E2E Test with enas-cnn-cifar10
 - E2E Test with mxnet-mnist
 - E2E Test with pytorch-mnist
 - E2E Test with simple-pbt
 - E2E Test with tf-mnist-with-summaries
 - Go Test
 - Lint YAML files
 - Publish AutoML Algorithm Images
 - Publish Katib Core Images
 - Publish Trial Images
 - Python Test
 - Shellcheck
