Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing metricflow functionality, rather than a Big Idea better suited to a discussion

Describe the feature

We need to update the dbt-jsonschema with new fields added to the spec. A community member flagged the following issues:

Hi Team,
Does the dbt YAML validator json at https://github.com/dbt-labs/dbt-jsonschema need to be updated for the latest? I'm looking at github.com/dbt-labs/jaffle-sl-template and see things not described in any of the validator schemas.
Examples:

• File models/marts/customer360/orders.yml contains metric orders_fill_nulls_with_zero with type_params including fill_nulls_with and join_to_timespine not found in validation schemas
• File models/marts/customer360/orders.yml contains metric twice_orders_fill_nulls_with_0 with type_params > metrics as a string. In the validation schemas it is an object with properties
• File models/marts/ecommerce/olist_closed_deals.yaml contains metric mql_to_seller_conversion_rate_7_day_window_with_filter with conversion_type_params not found in validation schemas
• File models/marts/ecommerce/olist_closed_deals.yaml contains metric mql_to_seller_conversion_rate_base with type: conversion which is not an expected enum value for type
• File models/marts/customer360/order_items.yml contains saved_queries not found in validation schemas
