Add a language prompt to the default-minimal template (#3918)

## Changes

This adds a language prompt (Python / SQL / other) to the
`default-minimal` template.

## Why

`pyproject.toml` and `conftest.py` are not relevant for non-Python DABs
projects like Apps projects.

## Tests

* Acceptance tests now exercise a non-Python minimal template
