jsonapi_reference 2.0.0-alpha3

#3092722: Provide a plain-text formatter for the TypedResourceObjectItem field type to provide further out-of-the-box functionality
#3337250: Use property promotion for $jsonapiClient in TypedResourceObjectStringFormatter
#3416675: JSON:API Reference fields cannot be configured on Drupal 10.2
#3330764: Add 'title' to field config to use as default for widget config
#3441052: Options using the same "search attribute"'s value are not all available

Note that #3441052 is a BC break because it changes the shape of the return from JsonApiClient::search(), which will break third party widgets.
