publication includes build directories

Bug description and behavior

See https://zenodo.org/record/6826881

it includes build, eggs...

Expected behavior?

The repository content is published as is

Possible fixes

1. git reset --hard HEAD && git clean -fd in snippet?

• this requires adding git in the docker image
• need to be careful with modified files during CI
• check that HEAD is indeed the latest tag

2. using gitlab zipball https://python-gitlab.readthedocs.io/en/stable/gl_objects/projects.html?highlight=zip#examples

• but this is tight to gitlab => make a eossr-gitlab-release command?
