transient dependency to node-sass has a dependency on python 2

I tried to set up a dev environment on my arch based linux machine and ran into this error:

available python versions: python 3.9

this seems to be the case because node-sass-chokidar has an outdated node-sass dependency which, in-turn, has tries to use python 2 with node-gyp sass/node-sass#3013

I checked the newest node-sass-chokidar version and they still depend on node-sass 4.x which has this problem.
I'll try to replace node-sass-chokidar with the native js version of dart sass
