bump Selenium version to 4.1 and remove deps in Examples project

[kapros]

Description

Bumping Selenium from 4.0 to 4.1 so that people can benefit from the packages. I also removed the dependency on Selenium in the Examples project - considering the tool itself provides that dependency, that leaves the solution with only 1 source of truth for package versions and easier to maintain by just updating the main package.

Testing

Testing was only limited to existing tests as I don't see any new tests being needed.
