Endpoint Modification for Template and savedQueries Retrieval with activated Validation

Issue: Endpoint Modification for Template and savedQueries Retrieval with Activated Validation

• There's a modification in the endpoint for template retrieval, transitioning to /query/template with activated validation. Additionally, an optional URL parameter ?validate=false is introduced to deactivate the validation process

• The retrieval process for 'savedQueries' follows the same schema as the modification in the endpoint for template retrieval.

This will most likely become v4 of the api unless agreed upon otherwise
