More detailed instructions in installing_this_repo.rst please!

Nobody has claimed this yet.

I appreciate the IDE agnosticism of that document, but I think examples for each step (for a specific IDE) would go a long way toward making this project accessible to new users.

Additionally (and arguably this should be a separate issue or issues), there is no mention of how to then run any of the examples once the project is set up correctly.

It also should be noted that this step is not even required to get started writing games as `.lud` files, as those may be loaded at runtime into the Ludii Player application. So if your goal is to write a game for Ludii, you do not need to install the tutorials repository at all.

Open installing_this_repo.rst and review the existing setup steps first. Add concrete examples for a specific IDE, explain how to run the examples after setup, and clarify that .lud files can be loaded into the Ludii Player without installing this repository; the document should cover these paths without ambiguity.
