Unpack draft object to key and text in commCoreModule updateDraft method signature

Summary: This differential addresses the following Linear urgent issue: https://linear.app/comm/issue/ENG-2374/jsi-codegen-broken-by-new-drafts-types. It is done by removing draft as argument type from updateDraft method and passing key and text directly.

Test Plan: 1. cd native && yarn codegen-jsi MUST work. 2. Launch flipper, type drafts, close the app. Open again and ensure that typped drafts are in the payload of setClientDBStore action. This way we simply ensure that modifying updateDraft on the C++ side didn't break draft-persistence functionality.
