Suggestion: provide examples in docs for how to push changes to enums across subgraphs (and avoid composition errors)

[magicmark]

specifically this scenario: https://github.com/apollographql/federation/blame/ba3175ec0fe450bdb3902b4893ff75c4f782d8b3/docs/source/schema-design/federated-schemas/reference/composition-rules.mdx#L442

it's unclear to readers how they would add a new enum without breaking composition. is there something we can link to?

Hello 👋
Thanks for the suggestion! Indeed this area should be clarified. While we are working on the doc updates see this thread from our community forums where Greg shows how to evolve the enums with @inaccessible.
