tests/unit/create/test_creator.py::test_create_no_seed --creator venv fails on Python 3.13 about virtualenv

[hroncok]

The related Python 3.13 change is python/cpython#108125

[hroncok]

Apparently:

$ virtualenv -p python3.13 testenv --no-seed --creator venv
created virtual environment CPython3.13.0.alpha.2-64 in 122ms
  creator Venv(dest=/home/churchyard/tmp/testenv, clear=False, no_vcs_ignore=False, global=False, describe=CPython3Posix)
  activators BashActivator,CShellActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator

$ cat testenv/.gitignore 
# Created by venv; see https://docs.python.org/3/library/venv.html
*

This either breaks the test expectation or virtualenv behavior.

Either we want the .gitignore file contents to be consistent (and hence we need to override it and/or opt-out of this feature) or we need to adjust the test to allow the venv-generated comment in it.

Which one do you prefer?

We want it to be consistent. Our ignore though should run after theirs, so we should overwrite what they create?

Do not generate/overwrite .gitignore if it already exists at destination path - by @gaborbernat. (#1862)

Huh! I think we should probably just adjust the test and also make sure that what we generate looks like what venv generates (mostly).

I started by #2672

The files only differ by the comment.
