# Description

Currently, the very first tutorial for users is the app launcher. This

launcher tutorial and puts it later in the part 1 of the tutorials.

# Description

Currently, the command to play a trained RL model is lacking the flag
that will make it use the latest checkpoint, despite that behavior
being described as expected in the surrounding text. This MR adds the flag.

It also removes a statement that 'by default' the above command will
load the latest checkpoint, because it could be potentially confusing as
that behavior is only 'by default' when you use the flag.

# Description

Our previous reasoning of not updating the sensors since the 'scene' is
not updated does not work well on resets. It was done assuming the
update is called right after reset. However, nowhere in the code, this
seems to be the case anymore.

This MR makes sure sensors are always updated when they are reset. The
reset method should set values to zeros or defaults when the sensor data
is invalid.

a wrong operation.

# Description

Earlier, the markers set "invisible" to secondary rays on the
wrong prim (XForm instead of mesh). For context, this property is used
when we don't want to see the marker prims on secondary rendering
operations used to compute depth and semantic images. However,
the markers are still visible on RGB.

This MR makes sure that the marker prims are invisible to these rays by
setting the property on the correct prim.

# Description

This MR reorganizes the sensor tutorials. Hence, there is only one sensor
tutorial introducing spawning sensors to an `InteractiveScene` and
some minimal tutorials for other sensors. The USD camera tutorial is
converted into a how-to save camera image.

Note: the how-to has to be fixed in a separate PR as we have to see what
is the best way to save images efficiently, the Replicator Writer might
have been updated in the meantime.

In `AppLauncher`, added self._livestream >= 1 to the list of conditions
which can cause omni.kit.widget.toolbar to be loaded, as this extension
is loaded later based in AppLauncher startup to remove the 'stop'
button, and this will cause a crash if not omni.kit.widget.toolbar is
not already loaded.

This is reproducible by using any 'experience' without toolbar enabled
while having LIVESTREAM=1. An example is the `--headless` execution in
our 'Training with an RL Agent' tutorial:
`./orbit.sh -p source/standalone/workflows/sb3/train.py --task
Isaac-Cartpole-v0 --num_envs 64 --headless`

The relevant babel function prefers to read timezone information from
the envar `TZ`, and so setting it in a Docker user's session prevents
this issue.

# Description

This MR started with fixing the Unitree A1 environment configuration.
The asset has the name "trunk" instead of "base" so had to be adapted in
the code.

Additionally, all the ANYmal environments were following a different
hierarchy system. This MR makes the inheritance tree more consistent
across all environments.

## Type of change
