(Doc+) Clarify dimension field requirements for time_series aggregation (#119442)
* (Doc+) Clarify dimension field requirements for time_series aggregation

👋 howdy, team!

This PR adds a note explaining that time series indices require:
- index.mode set to "time_series"
- at least one dimension field with time_series_dimension: true
- a routing_path array listing those dimension fields

Without these settings, the time_series aggregation may return empty buckets or behave unexpectedly. By emphasizing the dimension field requirement, we help users configure their time series indices correctly and see meaningful aggregation results.

* Apply suggestions from code review
