Make pagedjs vite.js compatible
Not really a regression: beta.20 now has better heuristics for prioritizing module field over browser, but pagedjs' module field points to a non-existent file because it doesn't ship its src dir when publishing.
Vite seems to be using the source to set up a proper treeshaking and modern budling.
Which mean that the src file should be published with the rest.
I think it totally makes sense, let’s do that when @fchasen is back.
