Drop support for Python 3.7

[jorenham]

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

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. $ pypistats python_minor datamodel-code-generator -t -f markdown

@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. https://github.com/pydantic/pydantic/pull/7188

[jorenham]

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

@jorenham I want to drop support Python 3.7 but the PR needs to be updated. I'm sorry. I will close the PR and recreate a new PR for it.
