Removes unneeded print

@youliangtan I removed one print statement to avoid clogging the terminal - could you take a look?

Oops @youliangtan looks like you don't have write access --- asking @zhuyifengzju to take a look

Shall we change it to debug logging messages?

[kevin-thankyou-lin]

Looking at the other .debug(), these are only used when there's something unexpected e.g.

                if part_name not in self._action_split_indexes:
                    ROBOSUITE_DEFAULT_LOGGER.debug(f"{part_name} is not specified in the action space")
                    continue

so I think using .debug() mightn't fit? Also, not sure how useful logging this is anyways - we only have this print statement for one file
