[graphql] composed queries

[bitbeckers]

As a developer, I want to be able to filter attestations on both schema and hypercert ID, so that I can query attestations for a specific hypercert by the creator.

{
  attestations(
    first: 10
    where: {eas_schema: {uid: {eq: "0x48e3e1be1e08084b408a7035ac889f2a840b440bbf10758d14fb722831a200c3"}}, hypercerts: {hypercert_id: {eq: "11155111-0xa16DFb32Eb140a6f3F2AC68f41dAd8c7e83C4941-236496245010052232107045352165078906961920"}}}
  ) {
    count
    data {
      data
    }
  }
}
