Update template options

[millerds]

Thank you for your pull request. Please provide the following information.

Removing the option to create an Angular project using the 'yo office' command.

1. Do these changes impact User Experience? (e.g., how the user interacts with Yo Office and/or the files and folders the user sees in the project that Yo Office creates)

   • Yes
   • No

   If Yes, briefly describe what is impacted.
   There is one less option for them to pick from.

2. Do these changes impact documentation? (e.g., a tutorial on https://learn.microsoft.com/en-us/office/dev/add-ins/overview/office-add-ins)

   • Yes
   • No

   If Yes, briefly describe what is impacted.
   We need to indicate that Angular is no longer a supported template. Instructions on how to add add-in functionality to a random framework would be nice to have.

3. Validation/testing performed:
   Ran automated tests (had to remove the test that looked for Angular)

4. Platforms tested:

   • Windows
   • Mac
