Local builds failing: missing intents.yaml and languages.yaml

[remy]

Running yarn build (and yarn start) shows that two files are missing (which means local build doesn't succeed):

[ERROR] Client bundle compiled with errors therefore further build is impossible.
Module not found: Error: Can't resolve '../intents/intents.yaml' in '/Users/remy/dev/developers.home-assistant/docs'

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

Module not found: Error: Can't resolve '../../../intents/languages.yaml' in '/Users/remy/dev/developers.home-assistant/docs/voice/intent-recognition'

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

Module not found: Error: Can't resolve '../../../intents/intents.yaml' in '/Users/remy/dev/developers.home-assistant/docs/voice/intent-recognition'

These two files are referenced here: supported-languages.md but are missing from the directory seen here.
