Documentation refers to a non-existing method `MultipartWriter.serialize()`

[vovanz]

Long story short

Working with Multipart documentation page refers to MultipartWriter.serialize() method several times.

But this method does not exist (anymore?) in the class aiohttp.MultipartWriter.

Expected behaviour

Methods mentioned in docs should actually exist :)

Actual behaviour

MultipartWriter.serialize() is mentioned in docs but does not exist.

Steps to reproduce

1. Open the "Working with Multipart" page in docs and CTRL+F all MultipartWriter.serialize() occurrences.
2. Open aiohttp.MultipartWriter reference and make sure that this method is not documented there.
3. Open the source at aiohttp/multipart.py and make sure that the serialize method is not defined.

Your environment

aiohttp==3.1.3
