fix(no_stopping_area): skip drawing a stop line in the case where the detected stop lines are goals (autowarefoundation#7280)

* Revert "fix(no_stopping_area): fix stopping in front of a no stopping area in parking on the shoulder (autowarefoundation#6517)"

This reverts commit 144b9c7.

* if the stop point is near goal(distance < 1m), no stopping area module does not insert stop line

* style(pre-commit): autofix

* Update planning/behavior_velocity_no_stopping_area_module/src/scene_no_stopping_area.cpp
