Make Vite sample code Firefox compatible

Browse source 
The current sample code for "Using Vite" works fine in Chrome, but causes errors in Firefox: 

`Error: import declarations may only appear at top level of a module`

In addition to many errors logged to the console, this also causes subtle bugs in Firefox (e.g. the highlighting in the diff editor didn't work).

The problem appears to be that Firefox requires an explicit `type: module` for the web workers.

The revised implementation for Vite takes this into account and has been tested successfully in Chrome and Firefox.
