Fabric Notebooks: autoformat code cell

Databricks already allows users to format code cells:

This works for Python and SQL code.

This provides several advantages:

• users don’t have to think about formatting; they just need to hit a button
• there is no more arguing between different devs concerning their individual formatting preference (because it is enforced centrally)
• if consistently applied (before every commit) GIT diff will be much cleaner because it will not include any ´pure formatting changes that had no functional impact
