fix(react-query): HydrationBoundary has strictly typed state (#9520)

* fix(react-query): HydrationBoundary has strictly typed `state`

Only type definition changes, the `state` parameter is now required and
must be `DehydratedState` (or nullish). Every case omitting this prop or
passing a different shape is a bug now caught by `tsc`. Correct code has
no action needed.

Closes #9323

* ci: apply automated fixes
