The main goal was upgrading werkzeug for CVE-2024-34069.
After switching to python 3.12, it proved more difficult with changes to
setuptools, etc. I decided to pull the pyproject from the main, and
utilize that, alone with updated dependencies. Small changes were needed
in various api changes, notably:

- flask change of request_ctx
- swagger_ui_bundle version change, default_template_dir change
- aiohttp middleware api slightly changed
- flask json change, using flask.json.provider

I believe these changes will have minimal impact to users, but the
changes are likely breaking for some, specifically, the move to latest
flask.

fixes spec-first#1969

aiohttp has conflicting requirements for latest updates, where python3.8
is deprecated. Remove 3.8 support to simplify the requirements to take
latest.

- fixup doc genenerator, using config from main. Too many issues
  encountered trying to get a working autoapi version to work with
sphinx. Decided to adopt a more recent version of sphinx and utilized
Connexion/main's docs/conf.py file.
- add pipeline builds for supported python
- snap werkzeug version to address CVE's
