Build Python 3.11 image

[krishanbhasin-px]

Could the Trame image be built against Python 3.11 as well as 3.9 and 3.10?

My two main points are:

• Trame and vtk already support Python 3.11 (I was running 3.11 before I dockerised my application)
• It would allow users to benefit from the performance boost of 3.11
  • specifically Interpreter startup is now 10-15% faster in Python 3.11., which would reduce the delay in spinning up the new Python process when a new wslink session is created
