Refactor Buff Ending Announcer to Aura Expiry

- Deleted LibGroupInSpecT-1.1.toc, LibStub.lua, and lib.xml files as they are no longer needed.
- Updated localization files (deDE.lua, enUS.lua) to reflect the change from "Buff Ending" to "Aura Expiry".
- Renamed BuffEndingAnnouncer module to AuraExpiry and updated references throughout the codebase.
- Adjusted options and configuration to align with the new module name.
- Updated readme to describe the new Aura Expiry feature instead of Buff Ending Announcer.
