The documentation build is failing

[kristiankyvik]

The docs build started failing about a week ago. More concretely, it seems like they started breaking after this PR got merged.

• I have tried to reproduce locally with no success
• I have looked at the files changed in PR ci: added codecov.io reporting #1039 but I am struggling to understand how those changes could be connected

Once this is fixed, we will build and serve the latest changes to the docs, that have already been merged.

I am still struggling to reproduce this locally.

Based on build logs, I see:

• It does seems to installs the toml package
• But later raises the "ModuleNotFoundError: No module named 'toml'" error.

My wild guess is that this could be related to the virtual environment setup, as in the venv we use to install the packages (including toml) is not the same one where we are executing the sphinx build command.

I do not have access to the instance running the documentation build, maybe @ErikBjare you can give me hand here?

UPDATE: I think found the source of the issue, I was partially right. See this. Pushing a fix based on proposed solution.

This has been fixed as per PR #1059
