No Perception Tutorial in ROS 2

[hello-jkoubi]

There is no Perception Tutorial in the ROS 2 Tutorials: https://docs.hello-robot.com/latest/ros2/perception.md

This needs to be updated here: https://github.com/hello-robot/hello-robot.github.io/blob/0.3/docs/overrides/home.html#L408
The correct one for perception is rviz_basics.md

The link at https://github.com/hello-robot/hello-robot.github.io/blob/0.3/docs/overrides/home.html#L409 is also broken, it should be voice_teleop.md

I updated the home page: hello-robot/hello-robot.github.io#24

We still need to update stretch_tutorials, could you please do this @hello-jkoubi? Thank you!

I have updated stretch_tutorials to remove the Perception Tutorial from ROS 2 Tutorials drop down menu.
