Every time dependencies in pyproject.toml have been modified (e.g. when
pulling in a newer version of the imcf-fiji-mocks package), Poetry's
lockfile has to be updated (otherwise the build workflow will start to
fail, complaining about the outdated file).
To do so, it's not sufficient to simply call poetry lock --no-update but
rather the Poetry wrapper script has to be used like this:
scripts/run-poetry.sh lock --no-update
