Add root_mean_squared_error and root_mean_squared_log_error

[vnmabus]

Motivation

The functions root_mean_squared_error and root_mean_squared_log_error were added in scikit-learn 1.4 and the squared parameter was deprecated in the functions mean_squared_error and mean_squared_log_error, and removed in version 1.6.

We need to add a FData-aware version of these functions and deprecate that parameter.

Desired functionality

• Add FData-aware functions root_mean_squared_error and root_mean_squared_log_error to the scoring module.
• Deprecate squared parameter in functions mean_squared_error and mean_squared_log_error.
