feat: add react-router test

[markdalgleish]

Added a test for React Router. I've successfully run this test locally so I've also added it to the workflows.

Thanks as always for all of your hard work on the project 🙏

how does this relate to remix? should it replace that or is it a different testsuite that adds extra coverage for vite?

[markdalgleish]

React Router v7 now has an official Vite plugin which supersedes Remix.

The Remix test could potentially be removed, but it might be a good idea to keep it for a while to ensure everything is working while the community migrates across.

@dominikg lets have the two for now. @markdalgleish, it would be good to remove the remix one soon though. I would consider this not that far from a major from any other framework and in that case, even if most users are initially in the prev version, we aren't testing them and only checking the latest were the main development is carried out. If you think that we should keep both remix and react router for more than a few weeks, I think we should discuss why that's the case.
