test(nebula_ros): add smoke tests

[mojomex]

PR Type

• Improvement

Description

Add smoke tests for all sensors: each smoke test launches Nebula with the sensor's default configuration and with launch_hw:=false.

In a later PR, launch_hw:=true should also be included, testing whether Nebula can be terminated when waiting for a connection.
