See #120 - trying various strategies, leading to update webpack. https://webpack.js.org/migrate/5/

Last error appears to derive from ├─┬ @babel/[email protected] https://github.com/ome/omero-parade/actions/runs/4668971663/jobs/8266784235?pr=121
so I tried reverting the upgrade, but that fails since previous version doesn't work with webpack 5

cc @jburel That's a whole day I've spent on trying to fix parade. Seems like the only solution is to downgrade Node to 16.
