admins (@moralejo @rlopezcoto @maxnoe ) have to check/update codecov token

Error: Codecov token not found. Please provide Codecov token with -t flag.
Warning: Codecov: Failed to properly create commit: The process '/home/runner/work/_actions/codecov/codecov-action/v4/dist/codecov' failed with exit code 1

@morcuended I added the token and restarted the jobs.

There are more warnings though due to outdated actions, could you update also the other actions? Mostly it's checkout and setu-python I think

Checkout action is already at the latest version, I updated setup python to v5, and changed the deprecated provision mamba by the setup micromamba action
