what is the bug

URDF preview would give an error saying xacro led to an error. However, when I manually source the setup script, xacro works:

bash ~/ros2_humble/install/local_setup.bash && xacro <path/to/r2d2.urdf> && env

and produces a valid urdf.

So, I went into the repo's code to update this line which would initially lead to the error notification when trying to preview:

xacroCommand = `bash --login -c "xacro '${filename}' && env"`;

I manually updated the above line to contain to bash ~/ros2_humble/install/local_setup.bash && xacro <path/to/r2d2.urdf> && env

Then, I re-generated a .vsix file and reinstalled the extension. After doing so, I don't get the error notification, but PreviewURDF gives me a blank screen.

Repro steps

<how to reproduce the bug. Please attach sample files or github repo if appropriate.>

1. Install ros2 humble from source (so it's not in the default /opt/ros/... location
2. Install xacro from source
3. Use the PreviewURDF function

expected behavior

I should see the robot URDF.
