 {{{
 #!CommitTicketReference repository="" revision="62107"
 Code Modernization: Fix `rest_convert_error_to_response()` handling of
 non-array error data when obtaining `status`.

 While the error data is normally an array, this is not guaranteed. This
 issue would have been detected by PHPStan rule level 9, since
 `WP_Error::get_all_error_data()` returns `mixed[]`.

 Developed in https://github.com/WordPress/wordpress-develop/pull/11307

 Follow-up to r61429.

 Props nateallen, desrosj, jorbin, mukesh27, westonruter.
 See #63430.
 Fixes #64901.
