hasura doesn't forward set-cookie header from action when action is a query type

### Version Information

Server Version: 2.6.0-beta.1
CLI Version (for CLI related issue): 2.6.0-beta.1

### Environment

OSS

### What is the expected behaviour?

Hasura should forward `set-cookie` header regardless of whether the action is a `Query` or `Mutation`

### Keywords

action, set-cookie, header

### What is the current behaviour?

Currently hasura only seems to forward the `set-cookie` header only if the action is a `Mutation`

### How to reproduce the issue?

1. create a webhook that set's a cookie
2. create a `Query` action that references the above created webhook
3. see hasura is not forwarding the `set-cookie` header

### Screenshots or Screencast

### Please provide any traces or logs that could help here.

### Any possible solutions?

When the action is a `Mutation` hasura forwards the `set-cookie` header successfully

### Can you identify the location in the source code where the problem exists?

No

### If the bug is confirmed, would you be willing to submit a PR?

I don't know haskell

Reproduce the issue with a webhook that sets a cookie, then compare a Query action with a Mutation action. Trace the action webhook response handling and add or update coverage so both action types forward the set-cookie header; done means the Query response matches the existing Mutation behavior.
