This PR updates coverage from 5.2 to 5.3.

Changelog

5.3

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

- The ``source`` setting has always been interpreted as either a file path or a
module, depending on which existed.  If both interpretations were valid, it
was assumed to be a file path.  The new ``source_pkgs`` setting can be used
to name a package to disambiguate this case.  Thanks, Thomas Grainger. Fixes
`issue 268`_.

- If a plugin was disabled due to an exception, we used to still try to record
its information, causing an exception, as reported in `issue 1011`_.  This is
now fixed.

5.2.1

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

- The dark mode HTML report still used light colors for the context listing,
making them unreadable (`issue 1009`_).  This is now fixed.

- The time stamp on the HTML report now includes the time zone. Thanks, Xie
Yanbo (`pull request 960`_).
