Bluetooth: Mesh: Fix not updating health publication message
Bluetooth: Mesh: Fix not updating health publication message

The bt_mesh_fault_update() API is meant for updating the publication
message and sending it out to the network, however it was missing the
necessary call to health_pub_update() which is responsible for
updating the publication message.

Fixes #15300
