Please describe the issue that you are experiencing

twine check fails when there are badges in th readme file.
Apparently the bug comes from this badge:
https://github.com/silx-kit/pyFAI/actions/workflows/python-package.yml/badge.svg

Please list the steps required to reproduce this behaviour

• pip install twine
• python -m build -s
• twine check dist/*

Anything else you'd like to mention?

Here is the issue of the project :
silx-kit/pyFAI#2157

I believe this is an issue to report to https://github.com/pypa/readme_renderer

[Ian Stapleton Cordasco]

Also based on the message, it seems to be an issue with the readthedocs badge, not the GitHub actions badge. But that also looks to be the only badge with a scale setting on it in restructured text. Without knowing why you have that or why that's a problem with readme-renderer on different versions of python, I can't really help here

[Jerome Kieffer]

Thanks for your input. Removing the reference to the scale allows to work-around this bug.
You are right, the issue is probably in the readme_renderer, project I was not aware about its existence.
Feel free to close the issue in twine.
