This PR updates coverage from 6.3 to 6.3.1.

Changelog

6.3.1

--------------------------

- Fix: deadlocks could occur when terminating processes.  Some of these
deadlocks (described in `issue 1310`_) are now fixed.

- Fix: a signal handler was being set from multiple threads, causing an error:
"ValueError: signal only works in main thread".  This is now fixed, closing
`issue 1312`_.

- Fix: ``--precision`` on the command-line was being ignored while considering
``--fail-under``.  This is now fixed, thanks to
`Marcelo Trylesinski <pull 1317_>`_.

- Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython
internal fields which are moving during the alpha phase. Fixes `issue 1316`_.
