Serialize payload to JSON formatted string

[HackAfro]

I realized that anytime my payload is in a dict format, I get this error while trying to send notifications.

To fix this issue, I had to use json.dumps on the payload. So I suggest either we fix the issue or advice the user to serialize the payload

In the documentation, its mentioned to import the function from webpush import send_user_notification not from utils. Its making the json.dump if you import directly from __init__.py. Check the __init__.py please.

I didn't import from utils. Here's what my imports look like:

I'm not importing directly from utils. This has happened a few times in a few of my projects and I had to spend time searching for the origin of the issue

Oh I see my mistake. I'm meant to import send_user_notification and not send_notification_to_user. That fixes it.

@HackAfro So I think this PR should be closed? what do you think?
