Add match schema update prek hook for Helm values_schema.schema.json file

[Miretpl]

Part of #68596 and follow-up to #70796.

Adding a script to automatically update the values_schema.schema.json file with the matching clause of properties from values.schema.json, based on the existing type fields in values.schema.json. This will ensure that if a new type is added to the values.schema.json file, the corresponding validation file will be updated as well.
