Types::AccessLevelEnum::UnresolvedValueError: `AccessLevel.stringValue` returned `60` at `project.environment.protectedEnvironments.nodes.1.dep...

Problem

When Protected Environment allows Admin role to deploy, the following GraphQL query results in 500 error.

{
  project(fullPath: "<path>") {
    name
    environment(name: "production") {
      name
      protectedEnvironments {
        nodes {
          group { name }
          project { name }
          deployAccessLevels {
            nodes {
              user {
                name
              }
              group {
                name
              }
              accessLevel {
                stringValue
              }
            }
          }
        }
      }
    }
  }
}

This is because Types::AccessLevelEnum doesn't define ADMIN: 60.

Proposal

Add ADMIN: 60 to Types::AccessLevelEnum.

Types::AccessLevelEnum::UnresolvedValueError: `AccessLevel.stringValue` returned `60` at `project.environment.protectedEnvironments.nodes.1.deployAccessLevels.nodes.2.accessLevel.stringValue`, but this isn't a valid value for `AccessLevelEnum`. Update the field or resolver to return one of `AccessLevelEnum`'s values instead.
