Issue:
Apparently the "main" field isn't right in package.json
```
(node:11234) [DEP0128] DeprecationWarning: Invalid 'main' field in '/node_modules/react-query/devtools/package.json' of '/index.js'. Please either fix that or report it to the module author
```

Pull request:
fix: Node 16 Invalid 'main' field warning from devtools
Simple fix to remove the `DeprecationWarning: Invalid 'main' field` warning that comes up now on Node 16.x . I just fixed the `main` and `module` paths in `devtools/package.json` to be relative to their current directory.

Fixes #2233

+## `queryClient.setQueriesData`
+
+`setQueriesData` is a synchronous function that can be used to immediately update cached data of multiple queries. Only queries that match the passed queryKey or queryFilter will be updated - no new cache entries will be created. Under the hood, [`setQueryData`](#queryclientsetquerydata) is called for each query.

 ## `queryClient.invalidateQueries`
 
 The `invalidateQueries` method can be used to invalidate and refetch single or multiple queries in the cache based on their query keys or any other functionally accessible property/state of the query. By default, all matching queries are immediately marked as invalid and active queries are refetched in the background.
