Add default-minimal template

[lennartkats-db]

Changes

Adds a new default-minimal template for advanced users who want a clean slate without sample code:

• Added default-minimal which inherits from the default template, just like default-python
• Enhanced template renderer to preserve empty directories (necessary to avoid .gitkeep files in src/ and resources/)
• Fixed uv run pytest error shown for projects that don't have a src/<package> directory

Why

Advanced customers and non-ETL customers (like @fjakobs) indicated they want an "empty" or "minimal" project template where they don't need to delete sample code. Rather than answering "no" to all questions in default-python, this gives them something more intentional.

Tests

• Template acceptance tests
• Manual uv run pytest, databricks bundle deploy, databricks bundle run on generated project

Example:

$ databricks bundle init default-minimal
Welcome to the minimal Databricks Asset Bundle template!
This template creates a minimal project structure without sample code, ideal for advanced users.
(For getting started with Python or SQL code, use the default-python or default-sql templates instead.)
Your workspace at https://e2-dogfood.staging.cloud.databricks.com is used for initialization.
(See https://docs.databricks.com/dev-tools/cli/profiles.html for how to change your profile.)
Unique name for this project [my_project]: empty
Default catalog for any tables created by this project [main]:
Use a personal schema for each user working on this project.
(This is recommended. Your personal schema will be 'main.lennart_kats'.): yes
✨ Your new project has been created in the 'empty' directory!
To get started, refer to the project README.md file and the documentation at https://docs.databricks.com/dev-tools/bundles/index.html.
