Add note about Official Docker Image default for load_examples

[uplsh580]

Related Issue

closes: #60722

Summary

Adds a note to the load_examples configuration documentation clarifying that the Official Airflow Docker Image sets this value to False by default, which overrides the default True value.

Problem

The Configuration Reference mentions that the default value for load_examples is True, but it doesn't mention that this is overridden in the official Docker image. This can be confusing for users who expect example DAGs to be present when they first run the official image but find them missing.

Solution

Added a note in the load_examples configuration description in config.yml to inform users about this behavior in the official Docker image and how to enable example DAGs.

Looks good to me! I'm not a committer, so my review does not hold much weight. But this LG!

Cool, LGTM 😉
Same comment as before — could we also update DAGs to Dags here for consistency?
