## Description
After discussion with the Starcraft team, it has been agreed on to move the `pebble` binary to `/usr/bin` instead of `/.rock/bin` for 24.04, since we're quite sure that the `/usr/bin` dir won't change for 24.04.
This PR builds over the previous PR https://github.com/canonical/rockcraft/pull/528 but replaces the pebble path for 24.04 and onwards to `/usr/bin`, and change .
