Document credentials.json

[matthewmrichter]

I installed this and ran it according to directions. Pip env set to Python 3.10. OS is MacOS Ventura. I'm getting a 'src/credentials.json not found` error.

✗ python3 analyzer.py --user <username>@gmail.com
Traceback (most recent call last):

    with open(client_secrets_file, "r") as json_file:
FileNotFoundError: [Errno 2] No such file or directory: 'src/credentials.json'

I don't see any documentation in the repo about credentials.
