Subject: [PATCH] Add missing diagnostic message for private method quick fix

Fixes #37782

The code fix logic for adding missing private methods already existed
in fixAddMissingMember.ts (code 90038), but the diagnostic message
was missing from diagnosticMessages.json.

Added 'Declare private method {0}' message with code 90038 to enable
the quick fix to appear in the IDE.
