Failed automatic README generation

[SirAionTech]

Describe the bug

When pre-commit executes the hook oca-gen-addon-readme, the following occurs:

Generate addons README files from fragments..............................Failed
- hook id: oca-gen-addon-readme
- exit code: 1

Traceback (most recent call last):
  File "/home/simone/.cache/pre-commit/repovulpicmx/py_env-python3/bin/oca-gen-addon-readme", line 8, in <module>

To Reproduce

Steps to reproduce the behavior:

1. pipx install pre-commit
2. git clone [email protected]:OCA/server-tools.git && cd server-tools
   Right now the repository is https://github.com/OCA/server-tools/tree/5577e14e231a7907c8869dcb638fd34178b6d8af
3. pre-commit install
4. Edit any file that generates the README (for instance attachment_queue/readme/DESCRIPTION.rst)
5. git commit --all

Expected behavior
The README is generated

Additional context
There has been some discussion about this but I can't find it anymore, this is similar to acsone/setuptools-odoo#55.

I'm opening the issue here instead of https://github.com/OCA/maintainer-tools because installing the package as described there ($ pipx install oca-maintainers-tools@git+https://github.com/OCA/maintainer-tools.git) allows to generate the readme correctly, so the problem might be with how the template tells pre-commit to install the package.
