Add patch for validation error types on inertia:install

[pricci1]

This is part of #215

As commented in that PR, this changes add the suggested inertia-rails.d.ts type overrides to the inertia:install generator.

Considering that the code examples in the documentation and the generators pass the errors as arrays, maybe the global re-export should be part of the setup guide or even the inertia:install generator.

Also, as suggested by @skryukov, a link to the yet-to-be-merged cookbook is included in the inertia-rails.d.ts file.

Thanks for the PR @pricci1!

I believe @bknoles has some pushback on this approach—maybe we should include the inertia_errors helper instead to align with Inertia.js types. I also tend to do that in the ShadCN starter, for example.

Another issue with this approach is the fragile nature of these type patches—that's a major downside to this approach tbh 🤔

@bknoles wdyt?

[pricci1]

I agree that it is quite fragile and another thing to maintain.

Feel free to close!

Yea, I like that we're documenting the "redefine the types" option but I don't want to bake it into the library. That said, I echo @skryukov to say thanks for the PR @pricci1 !
