class ErrorCollection in Drupal 10

To be used when the primary data is `errors`.

@internal JSON:API maintains no PHP API. The API is the HTTP API. This class may change at any time and could break any dependencies on it.

(The spec says the top-level `data` and `errors` members MUST NOT coexist.)
