Expected behavior

The test:e2e and test:unit scripts would not be in the package.json of custom function projects.

Current behavior

The test:e2e and test:unit scripts ARE in the package.json of custom function projects. They do not work. Try to run them and you get an error saying that "mocha" is not a recognized command.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Create project with yo office.
2. Choose either of the custom function project types.
3. Let the project be created.
4. Open the package.json.
5. The two test scripts are still in it.

Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• Operating System: Win11
• Node version: 16.13.1

• Tool version: latest, just installed

Failure Logs

Please include any relevant log snippets, screenshots or code samples here.

Start at the yo office generator path for the two custom function project types and inspect the package.json template or generation step. Confirm how test:e2e and test:unit are added, remove them from custom function projects, and generate a project to verify those scripts are absent while other project types remain unchanged.
