Typescript optional values should also be "key optional"

[sean256]

As of now the type definitions require this

await conn.reducers.updateCategory({
  id: BigInt(1),
  name: 'updated category name',
  buttonText: undefined,
  headerText: undefined,
  deleted: undefined,
});

However, the following works just fine, except for type errors

await conn.reducers.updateCategory({
  id: BigInt(1),
  name: 'updated category name',
});

Argument of type '{ id: bigint; name: string; }' is not assignable to parameter of type 'InferTypeOfRow<CoerceRow<{ id: U64Builder; name: OptionBuilder<StringBuilder>; buttonText: OptionBuilder<StringBuilder>; headerText: OptionBuilder<...>; deleted: OptionBuilder<...>; }>>'.
  Type '{ id: bigint; name: string; }' is missing the following properties from type 'InferTypeOfRow<CoerceRow<{ id: U64Builder; name: OptionBuilder<StringBuilder>; buttonText: OptionBuilder<StringBuilder>; headerText: OptionBuilder<...>; deleted: OptionBuilder<...>; }>>': buttonText, headerText, deleted

The reducer in question

const updateSchema = {
	id: t.u64(),
	name: t.string().optional(),
	buttonText: t.string().optional(),
	headerText: t.string().optional(),
	deleted: t.bool().optional(),
};

export const updateCategory = db.reducer(updateSchema, (ctx, input) => {
	/**update code here**/
});
