Use `-> None` in script templates by default
<!-- Provide a general summary of your proposed changes in the Title field above -->
### Description
When working together with `mypy` we have a problem with the default template.
`mypy` raises errors on all migrations when used with https://mypy.readthedocs.io/en/stable/config_file.html#confval-disallow_untyped_defs
So, there are several options:
1. Remove this flag for `[mypy-db.alembic.*]` in `mypy.ini`. This is not a very good idea, because custom code that might get written in this directory might be not fully typed.
2. Edit our own template. This is what we end up doing right now, but this requires some manual work and many users might miss it
3. Update the source! I think that this is harmless (because only python3.6+ is supported), but allows better type-checking
### Checklist
Openning this as a draft for now. Will fix tests after I can see what is failing in the CI.
Issue is also on its way! 🙂
