**Describe the bug**

- when having the text that is stored in `./graphiql-not-caching-requests` in the
graphiql playground the @envelop/response-cache plugin does not cache
requests.
- when having the text that is stored in `./graphiql-caching-requests` it will

**To Reproduce**
Steps to reproduce the behavior:
- clone https://github.com/xddq/envelop-respones-cache-graphiql-issue
- `yarn`
- `yarn build`
- `yarn start`
- go to `localhost:4000/graphql` and copy paste the text of
`./graphiql-not-caching-requests`. Then run "hello" and see that it won't be
cached.
- go to `localhost:4000/graphql` and copy paste the text of
`./graphiql-caching-requests`. Then run "hello" and see that it will be
cached.

**Expected behavior**

- Cache results of the "hello" query in both cases

**Environment:**

- OS:
- NodeJS:
- `@envelop/*` versions: 3.0.0
- `@envelop/core`: 2.4.0

**Additional context**
I am not sure why this is happening. One thing I did notice that when testing that the other caching plugins `@envelop/parser-cache` and `@envelop/validation-cache` still work as usual. I also don't think that this bug is severe, since it occurs only if we have the introspection query in graphiql.
