(fix typo) change port to 7860

[thomasht86]

Why

There is a typo in port number for running custom python spaces through the gradio sdk.
Fixing so that others won't find out the hard way like me.

Sidenote:
I think this is an under-emphasized way of setting up a space.
Consider for example deploying a FastHTML app to spaces, is actually as simple as

from fasthtml.common import *

app,rt = fast_app()

@rt('/')
def get(): return Div(P('Hello World!'), hx_get="/change")

serve(port=7860)

Which means that you can remove a lot of complexity of deploying to a space.
As of now, the recommended approach is to use https://github.com/AnswerDotAI/fasthtml-hf, but this is way easier imho.
Creating a space template for FastHTML would also be nice.
