Fix Sphinx docs build: set language to 'en' instead of None

Adam Dobrawy · claude · Adam Dobrawy · commit 06e173afb397 · 2026-03-07T12:53:48.000+01:00
Sphinx 7.x treats `language = None` as an invalid configuration value
and errors out when using `-W` (warnings as errors). Setting it to "en"
resolves the build failure.
