https://github.com/direnv/direnv/commit/af06cb05c1468f4b80a7548818d096625fb04c36 indicates the upstream direnv fix.

Reproducible: Always

Steps to Reproduce:
1. $ sudo dnf -y install direnv
2. $ echo eval "$(direnv hook bash)" >> ~/.bashrc
3. $ mkdir ~/project-a
4. $ python -m venv ~/project-a/.venv
5. $ cd ~/project-a
6. $ echo 'layout python3' > .envrc
7. $ direnv allow

Actual Results:  
[vagrant@localhost ~]$ cd project-a/
direnv: loading ~/project-a/.envrc
<string>:1: DeprecationWarning: 'pkgutil.find_loader' is deprecated and slated for removal in Python 3.14; use importlib.util.find_spec() instead
  import pkgutil as u, platform as p;ve='venv' if u.find_loader('venv') else ('virtualenv' if u.find_loader('virtualenv') else '');print('.'.join(p.python_version_tuple()[:2])+' '+ve)
direnv: export +VIRTUAL_ENV ~PATH


Expected Results:  
direnv invokes the venv without throwing the exception.
