separate codemeta.json from the archive prevents mybinder to build the record from zenodo

Bug description and behavior

separate codemeta.json from the archive prevents mybinder to build the record from zenodo

Steps to reproduce

Trying to build record https://zenodo.org/record/5592836#.YfA4f_VKj0o into mybinder returns: https://mybinder.org/v2/zenodo/10.5281/zenodo.5592836/

The zip archive is not opened and thus the environment is not installed as expected.

Expected behavior?

The environment is built correctly and the user can access the content of the repo.

Here building from the gitlab repository directly: https://mybinder.org/v2/git/https%3A%2F%2Fgitlab.in2p3.fr%2Fchristopher.eckner%2Fmlfermilatdwarfs/HEAD

Relevant logs and/or screenshots

Possible fixes

• Abandon the separate codemeta archival? This could lead to other problems such as the necessity to download the whole record to read the metadata in codemeta...
• Not zip content
