[DOC] Anomaly detection getting started notebook

[SebastianSchmidl]

Describe the issue linked to the documentation

Aeon is still missing the anomaly detection getting started notebook (linked from the home page): https://www.aeon-toolkit.org/en/stable/examples/anomaly_detection/anomaly_detection.html

PR #1932 introduced some general documentation in the API documentation that needs to be moved to this notebook as well.

Suggest a potential alternative/fix

I already created an example notebook for one of our tutorials. It can be used as a starting point: https://github.com/aeon-toolkit/aeon-tutorials/blob/main/ECML-2024/Notebooks/part6_anomaly_detection.ipynb
