Description

This PR makes the following:

• Updates the setup of the Java test examples (Maven).
• Update and fix the tests examples (to be properly executed with mvn test).
• Create a GH actions workflow to run the Java tests with Maven.

Motivation and Context

To warranty that the test example shown in the Selenium doc is coherent, they should be executed on CI. This PR contributes to achieving that goal by implementing a step in that direction, i.e., executing the Java tests. If everything is correct, I can send other PRs for the rest of the test examples in other language bindings.

Types of changes

• Change to the site (I have double-checked the Netlify deployment, and my changes look good)
• Code example added (and I also added the example to all translated languages)
• Improved translation
• Added new translation (and I also added a notice to each document missing translation)

Checklist

• I have read the contributing document.
• I have used hugo to render the site/docs locally and I am sure it works.
