AttributeError in _iter_lines: 'str' object has no attribute 'search'

Hi, I stumbled on this regression after upgrading from 2.0.4 to 2.1.1 and calling format_exc() in an except: block

  File "/opt/nautobot/jobs/nautobot_ssot_xxx.py", line 1380, in sync_data
    self.logger.debug("```\n%s\n```", format_exc())
  File "/opt/nautobot/.local/lib/python3.9/site-packages/traceback_with_variables/core.py", line 102, in format_exc
    return '\n'.join(iter_exc_lines(
  File "/opt/nautobot/.local/lib/python3.9/site-packages/traceback_with_variables/core.py", line 177, in _iter_lines
    if bool(fmt_.skip_files_except) and all(not p.search(filename) for p in fmt_.skip_files_except):
  File "/opt/nautobot/.local/lib/python3.9/site-packages/traceback_with_variables/core.py", line 177, in <genexpr>
    if bool(fmt_.skip_files_except) and all(not p.search(filename) for p in fmt_.skip_files_except):
AttributeError: 'str' object has no attribute 'search'

the exception raised was of type pydantic_core._pydantic_core.ValidationError

Hi, I can't understand the reason for that, hmmm... It looks like ".skip_files_except" contains strs, but it has to contain only re.Patterns.

Could you pls provide minimal code example and how you run it? Like
def main(): return 1/0

I've been trying to come up with a simple example that reproduces the issue but so far I didn't have much luck.
The error shows up in a nautobot 2.3.12 plugin which uses django ~4.2.16, pydantic==2.10.3, diffsync==2.0.1 but it's a monster of a project to setup
