[falsetru]

My application breaks after upgrading to drf_orjson_render 1.4.0

I think this is caused by ORJSONRenderer.media_type change in 9dddb21#diff-af3668e3a8a4fd6a0dcb9a8d9a2550ac2f7fb3e562e2f5f94be73b28b0770684L21

In 1.3:

>>> from drf_orjson_renderer.renderers import ORJSONRenderer
>>> ORJSONRenderer.media_type
'application/json'

In 1.4:

>>> from drf_orjson_renderer.renderers import ORJSONRenderer
>>> ORJSONRenderer.media_type  # None
