Fix Static Analyse failure by declaring apiCode in ExtensionStoreApiException generator type

[Copilot]

Static Analyse was failing in CI because ExtensionStoreApiException::getErrors() yielded an extended error payload (apiCode) that was not represented in the method’s declared generator value shape. PHPStan treated this as a contract violation.

• Root cause

  • getErrors() merges parent error entries with an additional apiCode key.
  • The generator return type did not explicitly include apiCode, so yielded values were inferred as incompatible.

• Change made

  • Added an explicit PHPDoc return type to ExtensionStoreApiException::getErrors() that includes apiCode in the yielded array shape.
  • No runtime behavior changed; this is a type-contract alignment for static analysis.

• Code update

  /**
   * @return \Generator<int, array{
   *   code: string,
   *   status: string,
   *   title: string,
   *   detail: string,
   *   meta: array{documentationLink: string},
   *   trace?: string,
   *   apiCode: string
   * }>
