Minor Changes

• Update license field in package.json to use Elastic-2.0 SPDX identifier (#2741)

• Introduce the new @policy scope for composition (#2818)

  Note that this directive will only be fully supported by the Apollo Router as a GraphOS Enterprise feature at runtime. Also note that composition of valid @policy directive applications will succeed, but the resulting supergraph will not be executable by the Gateway or an Apollo Router which doesn't have the GraphOS Enterprise entitlement.

  Users may now compose @policy applications from their subgraphs into a supergraph.

  The directive is defined as follows:

  scalar federation__Policy
  
  directive @policy(policies: [[federation__Policy!]!]!) on
    | FIELD_DEFINITION
    | OBJECT
    | INTERFACE
    | SCALAR
    | ENUM

  The Policy scalar is effectively a String, similar to the FieldSet type.

  In order to compose your @policy usages, you must update your subgraph's federation spec version to v2.6 and add the @policy import to your existing imports like so:

  @link(url: "https://specs.apollo.dev/federation/v2.6", import: [..., "@policy"])
