Global axes labels bug

[Jakubach]

Hello, running the below example from the readme:

T = SE3(1, 2, 3) * SE3.Rx(30, 'deg')
T.plot()
plt.show()

gives me the plot with the global axes marked as "XXX" instead of "XYZ".

I work on Windows 11, with Python 3.8 and I was using the latest snapshot installed with: pip3 install roboticstoolbox-python[vpython] sympy

PS. for tranimate function it works fine
