Drop support for Python 3.7

[jorenham]

Also removed old python 3.6 code, and increased the upper bound of some deps

[jorenham]

The CI seems to be complaining about issues irrelevant to this particular PR.

The failing tests can be replicated by checking out the master branch and a poetry update.

@jorenham
Thank you for creating the PR.
Before we merge the PR. I want to check the active users of Python 3.7.
I understand the version is EOL. But I guess some projects may use the library in Python 3.7

I have run the cli to get the activity of this month.

@koxudaxi It's rather sad to see that there are more that twice the amount of 3.7 users than 3.11...

This is the real world😅

We should wait for pydantic itself to drop 3.7.
This is probably because pydantic is often used in the same project.
pydantic/pydantic#7188

[jorenham]

@koxudaxi That makes sense. I'll try again in a couple of years then 😛

[jorenham]

@koxudaxi pydantic/pydantic#7188 has been merged; time flies!

@jorenham
I agree with you it's to drop support 3.7 from runtime support list.
Should we delete PY_37 for output?
Personally, I'm happy to drop the old version from the output model list.
But I want to think about it again. 🤔
