our package.json script names have new interpretations in newer yarn

[WULCAN]

On e5d3297, both our package.json define scripts with a characted ':' in their name.

This is no problem in old versions of yarn but in newer versions scripts named like this are global scripts which is probably not what we intended here.

Out git runner is ubuntu-latest which has yarn 1.22.21 but as ubuntu-latest is a floating version, this can change at any time.

I'm not entirely sure if this is really the version of yarn used in our CI. It's possible but undocumented if setup-node@v4 installs and uses another yarn when node-version is set to 18.x

To prioritize this issue, we need to learn more about how global scripts are interpreted in newer versions.
