> Add {{SqlAlterMaterializedTableResetConverter}} under {{{}org.apache.flink.table.planner.operations.converters.materializedtable{}}}. Register it in {{{}SqlNodeConverters#registerMaterializedTableConverters{}}}.
> *Behavior:*
>  # Resolve the table from the catalog. Reject with {{ValidationException}} if the target is not a materialized table or does not exist.
>  # Remove the specified keys from the existing table options.
>  # Reject reserved keys, using the same allowlist applied in sub-task 1.
>  # Emit {{AlterMaterializedTableChangeOperation}} so the change flows through {{{}CatalogManager#alterTable{}}}.
> *Tests:*
>  * Single-key and multi-key reset.
>  * Reset of an option that was set via {{SET}} in sub-task 1, asserting the option is gone.
>  * Reject reserved keys.
>  * IT case that resets a known key end to end.
