samples: bluetooth: typo in project name

Corrected a typo in the project name within the Bluetooth
samples directory. The incorrect name was causing confusion
in documentation and build processes. This change updates
the relevant file(s) to use the correct project name, ensuring
consistency across the Zephyr repository.
