Describe the workflow you want to enable

As I had added root_mean_squared_log_error previously in #20326 . Now I want to register the same in sklearn.metrics.scorers . You can see #20326 (review) for better understanding.

Describe your proposed solution

The solution is to add a parameter named squared which will be false by default and when it'll be set to true then the function will return root of mean_squared_log_error .

Describe alternatives you've considered, if relevant
