📜 Description

Feat: Add locale to device context and deprecate language
language now returns only the language eg en instead of en_US, since the language field was never indexed, its not a breaking change on discover and alerts

💡 Motivation and Context

language was actually the locale, and locale was missing.
Closes #1834
