Add pyproject async template to Alembic

[Alc-Alc]

Description

This PR adds a new template "pyproject_async"^* that can be used to bootstrap environments that want to use async DB-API with a pyproject.toml file. It also includes a minor update to the cookbook to add the name of the new template.

PR is similar to 8196af9 that added an async template.

this is just the async + pyproject templates put together right? should be fine

Appreciate the quick response. Yes, it is just async + pyproject.

Hey @zzzeek / @CaselIT, can you let me know if there is something wrong with this PR so I can fix it or is it an unrelated failure?

the pep8 stuff clearly has to do with the newer releases of flake8-import-order, I'll fix all that

I think it may need changes to zimports to fix. We could pin that plugin for now

Sorry, wrong button

[zzzeek]

yes, got the new zimports in, the fix w/ the type-checking is a lifesaver
