Do not prompt for confirmation for GraphQL queries without a mutation

[gr2m]

Sending a GraphQL query is currently a POST /graphql request, so even if the query does not perform any mutation, the CLI is prompting the user to confirm the request

? Do you want to allow the following request:

  <unknown endpoint>
  route:     POST /graphql
  query:     query($htmlUrl: URI!) {
      resource(url: $htmlUrl) {
        ... on PullRequest {
          state
          author {
            login
          }
          files(first:2) {
            nodes {
              path
            }
          }
          commits(last: 1) {
            nodes {
              commit {
                oid
                checkSuites(first: 100) {
                  nodes {
                    checkRuns(first: 100) {
                      nodes {
                        name
                        conclusion
                        permalink
                      }
                    }
                  }
                }
                status {
                  state
                  contexts {
                    state
                    targetUrl
                    description
                    context
                  }
                }
              }
            }
          }
        }
      }
    }
  variables: [object Object]

❯ yes
  no
  yes, for all "POST /graphql" requests
  yes, for all requests

They way to go will be to use graphql-tag to turn the query into an AST, then check if the query includes a mutation

const gql = require("graphql-tag");
const ast = gql(query);
const queryHasMutation = ast.definitions.filter(({ operation }) => operation === "mutation");
