fix: point Task 2 starter branch to week-13-ch-4-dbt

[lassebenni]

Summary

• task-2/README.md still referenced non-existent week-13-databricks on nyc-taxi-dbt-reference.
• Point students at the real starter branch: week-13-ch-4-dbt (not -solution, which is the Ch4 answer sheet).

How to review

• One-line change in task-2/README.md.

Secrets hygiene checklist

• No .env or profiles.yml files committed.
• No Databricks personal access tokens (dapi...) hardcoded.
• profiles.yml.example and .env.example templates present.
