Component does not work with Vaadin 23.3

[probert94]

I tried upgrading my project from Vaadin 23.2 to 23.3.
Unfortunately I get the following error:
SyntaxError: The requested module '/VAADIN/generated/jar-resources/print-js/dist/print.js' does not provide an export named 'default'

The issue can be reproduced with a Vaadin starter:

1. Add vcf-pdf-viewer 2.5.2 as a dependency.
2. Add the following code to MainView.java:

    public MainView() {
        PdfViewer pdfViewer = new PdfViewer();
        StreamResource resource = new StreamResource("example.pdf", () -> getClass().getResourceAsStream("/pdf/example.pdf"));
        pdfViewer.setSrc(resource);
        pdfViewer.openThumbnailsView();
        add(pdfViewer);
    }

It seems like there is a problem with pdf-js and vite but we are already using Vaadin 23.2 with vite so the issue is not related to vite only.

PDF.js a such is not fully, compatible with vite: see mozilla/pdf.js#10317 (comment)

However workaround may exists to import the worked differently https://erindoyle.dev/using-pdfjs-with-vite/

Meanwhile, there is webpack fallback option in Vaadin 23, which allows to use the add-on in the current form.

I forgot to mention, that we are already using Vaadin 23.2 with vite, so its not (only) a vite issue.
I think it might be related to a stricter typescript validation in vaadin 23.3, as we got a lot of typescript related errors when trying to update.
