Using the map causes a "ReferenceError: module is not defined" in browser

[BesitecMH]

Describe the bug I just added the add-on to my project. Running the application and opening the page in browser causes a Javascript error breaking the startup. (Using Vaadin 23.5.2) The browser's console reports a "ReferenceError: module is not defined" with a link. The link leads to the "Sources" where the "leaflet-canvas-marker/node_modules/rbush/index.js" show the error for code line "module.exports = rbush".

I have the problem with my complex project while upgrading from Vaadin 14 to 23. (Previously used the predecessor add-on of this one.) I could not reproduce with a Vaadin 23 skeleton project. But Markus from chat support could in the first step. Later, playing around with the add-on's version, the error vanished also from his example.

To Reproduce Steps to reproduce the behavior:

1. Download: https://github.com/vaadin/skeleton-starter-flow/archive/v23.zip
2. Add add-on dependency to pom.xml (version 1.0.1)
3. Needed also to add the following not to get a Jackson error on startup

   <dependency>
   <groupId>de.grundid.opendatalab</groupId>
   <artifactId>geojson-jackson</artifactId>
   <version>1.13</version>
   </dependency>

4. Add code snippet from to MainView: https://vaadin.com/directory/component/leaflet
5. Run application

Expected behavior The error should not appear ;-)
