[Bug] Extraneous lines in traceback log in Python Panel

[nilason]

Describe the bug

In case of Python error the traceback log is presented in the Pyton Panel with extraneous lines (empty or with a caret), causing the interpretation of the message difficult, or–worse–the actual error may be overlooked.

  File "/dev/grass/dist.aarch64-apple-
darwin23.6.0/gui/wxpython/lmgr/layertree.py", line 1130, in
