This change removes the custom sim parameters used for the
`Isaac-Stack-Cube-Franka-IK-Rel-v0` env, setting it to use the same sim
parameters as the base environment config class and aligning it with the
other Franka stacking environments. This change increases simulation
stability and performance.
