CE-1965: fix cicd chokidar filewatchers error

Closes CE-1965

requested review from @alexandermadsen, @domonkosgulyas, and @imretoth

Before: https://gitlab.esss.lu.se/ccce/dev/ce-deploy-ui/-/jobs/347850

After: https://gitlab.esss.lu.se/ccce/dev/ce-deploy-ui/-/jobs/347862

Note that https://gitlab.esss.lu.se/ccce/dev/ce-deploy-ui/-/jobs/347862 failed due to the whole pipeline taking an hour to run in GitLab, and timed out. This is most likely a separate issue considering running that same pipeline locally takes less than 5 minutes on my computer. :/

Main point is that the Chokidar errors are gone now...which ironically might even help with the performance problems.

It may be a dumb question, but from react-script 5.0 isn't the WATCHPACK_POLLING=true suggested to be used?

I see true being used here: https://create-react-app.dev/docs/advanced-configuration/ but never seen it being suggested anywhere, but that being said I do prefer true vs 1 for pure visual clarity.

https://gitlab.esss.lu.se/ccce/dev/ce-deploy-ui/-/jobs/348734 looks great, but I'll update per Alexander's comment first.
