Fix some dependency issues and remove obsolete try-except block

[fpgmaas]

Since #955 was closed with the reason that there was no interest in adding another step to the CI pipeline, it might still be worthwhile to resolve some issues with the project's dependencies without adding deptry to the project or the CI pipeline. This PR:

• Removes the obsolete try-except blocks for importing pyairports and pycountry, since they are listed in the project's dependencies.
• Add the transitive dependency typing_extensions to the dependencies
• Remove ray as a development dependency

Let me know your thoughts :) Feel free to close if you think it does not bring improvement to the project

@rlouf do many users use Outlines in a way which doesn't require torch? The only models which don't require torch AFAIK are models.llamacpp, models.mlxlm and models.openai.

@fpgmaas Could you rebase and squash this to one or two commits?

Edit: sorry, wrong remi

done!

torch is a really big dependency and I would rather not force it on people who don’t need it; especially libraries that import outlines just for the FSM logic (vLLM, etc)
