Documentation: Use language 'en' for Sphinx 5.0.0

Recent versions of Sphinx (> 5.0.0) have dropped support for the
'None' keyword as language specifier:

https://www.sphinx-doc.org/en/master/changes.html#release-5-0-0-released-may-30-2022

10474: language does not accept None as it value. The default value of
       language becomes to 'en' now. Patch by Adam Turner and Takeshi
       KOMIYA.

Causing a compile time warning:

WARNING: Invalid configuration value found: 'language = None'.
Update your configuration to a valid language code. Falling
back to 'en' (English).

Change the language setting to 'en' to silence the warning.
