fix: Hande variables

[ChaituVR]

Previously we were ignoring variables passed into the body, now that we use other subgraphs, we need to pass variables as well

How to test:

Pass variables to subgraphs

curl --location 'http://localhost:3000/subgraph/arbitrum/5XqPmWe6gjyrJtFn9cLy237i4cWw2j9HcUJEXsP5qGtH' \
--header 'accept: application/json, multipart/mixed' \
--header 'accept-language: en-US,en;q=0.9' \
--header 'content-type: application/json' \
--data '{"query":"query Domain($id: ID!) {\n  account(id: $id) {\n    domains {\n      name\n      expiryDate\n    }\n    wrappedDomains {\n      name\n      expiryDate\n    }\n  }\n  domains(block:{number: 20074255}){\n    id\n  }\n}","variables":{"id":"0x24f15402c6bb870554489b2fd2049a85d75b982f"}}'
