Update webargs to 4.2.0

[pyup-bot]

This PR updates webargs from 4.1.3 to 4.2.0.

Changelog

4.2.0

******************

Features:

* Add ``force_all`` argument to ``use_args`` and ``use_kwargs``
(:issue:`252`, :issue:`307`). Thanks :user:`piroux` for reporting.
* The ``status_code`` and ``headers`` arguments to ``ValidationError``
are deprecated. Pass ``error_status_code`` and ``error_headers`` to
`Parser.parse`, `Parser.use_args`, and `Parser.use_kwargs` instead.
(:issue:`327`, :issue:`336`).
* Custom error handlers receive ``error_status_code`` and ``error_headers`` arguments.
(:issue:`327`).
