[v5] lowercase filenames breaks imports

Created by: nlemoine

Hi,

I'm using latest version of bootstrap (master). Until now, I built my js bundle (with rollup) on my local laptop (Mac OS, unsensitive case filesystem).

The file looks like:

import 'bootstrap/js/dist/carousel';
import 'bootstrap/js/dist/collapse';
import 'bootstrap/js/dist/modal';

Works like a charm. Until I setup a CI to do the build job for me.

Could not resolve './dom/eventHandler.js' from node_modules/bootstrap/js/dist/carousel.js

I guess this error is caused by require('./dom/eventHandler.js') whereas the filename is eventhandler.js.

Maybe filenames should adopt another standard to be more consistent (lower with dashes)?
