Update added-mass of lrauv model and remove added mass definitions from examples

🦟 Bug fix

Fixes #2575

Summary

Since, we have decided to deprecate added mass in the hydrodynamics plugin in favor of using the SDFormat fluid_added_mass tag (See #2493 ), we should update our examples to avoid the warning.

TODO: Update maritime tutorials and migration guide.
