feat(amazonq): Copy changes for falcon features (#6703)

Problem:
- We need to update copy text

Solution:
- Move hardcoded strings to language file
- Update titles/descriptions of new Context menu options
- Update welcome message to include new context menu options
- Update mynah-ui to latest
- add changelog for all falcon features
