Mutation query responses may be cached

[jerrysu]

Both useMutation and useBulkMutation may end up using cached query responses if the action doesn't change between mutations (e.g., the POST data remains the same). It seems wrong to me that mutations would be cached.

The query function has a skipCache flag that needs to be set on these two lines:

react-fetching-library/src/hooks/useMutation/useMutation.ts

Line 50 in 9b0abd8

const queryResponse = await clientContext.query<T>({ ...action, signal: action.signal || signal });

react-fetching-library/src/hooks/useBulkMutation/useBulkMutation.ts

Line 66 in 9b0abd8

const queryResponses: Array<QueryResponse<T>> = await Promise.all(actions.map(action => query<T>(action)));

I'll submit a PR for this after I free up some time.

Actually, now that I think about it, this is an issue for us because we want to cache some POST requests that we use with useSuspenseQuery. This is actually more of an issue with the design of our API.
