Describe the issue linked to the documentation

Related Issue: #2066

The newly implemented range_metrics module in the Anomaly Detection section, which includes the functions ts_recall, ts_precision, and ts_fscore, is currently not included in Aeon's API documentation.

This module replaces the now-deprecated functions range_recall, range_precision, and range_f_score.

Suggest a potential alternative/fix

Add the range_metrics module to the API reference documentation.
