Describe the issue

Running latest git with python/3.12.0 ran into the following error for python/open3d/visualization/tensorboard_plugin/summary.py

line 427 f"{tensor.shape[k-1] for tensor in tensor_tuple}.") ^^^ SyntaxError: f-string: expecting '=', or '!', or ':', or '}'

AI suggested changing to: f"{[tensor.shape[k-1] for tensor in tensor_tuple]}." which has allowed the code proceed/run but presumably alters the output.

Steps to reproduce the bug

Apologies - don't have sharable code to replicate at this time
