WordPressDataIngester::_get_filesize should not use get_response_json

[AetherUnbound]

Description

The WordPress Photo Directory data ingester's _get_filesize method is presently attempting to use ProviderDataIngester::get_response_json on an endpoint which is not JSON:

This is giving us the following error:
