fix(autoware_pointcloud_preprocessor): remove unused arg and unavailable param file.

[mbharatheesha]

Description

This PR removes an unused launch argument from preprocessing filters in the autoware_pointcloud_preprocessor package and fixes #9524

Parent Issue:

• Link Unavailable param file prevents individual preprocessor nodes from starting #9524

How was this PR tested?

Removing the unused launch argument and hence unavailable path to the non-existent param file starts the filters properly. I tested this with the crop_box_filter_node.
