Typescript only stack support

[meza]

What version of Remix are you using?

@latest

Are all your remix dependencies & dev-dependencies using the same version?

• Yes

Steps to Reproduce

1. create a stack that is typescript only
2. use the stack with npx create-remix@latest --template your/stack
3. choose to not have typsecript
4. observe as remix tries to do transformations it can't

Expected Behavior

I'd expect this question to simply not exist. It should be up to the stack maintainers to offer all the transformations that a user is allowed to do on them automagically

Actual Behavior

Remix tries to remove the tsconfig and modify the remix config among other things.

Instead of allowing the custom stack to carry on, the user is greeted with a failure and no way of continuing.

Thanks for raising this issue. The new version of create-remix that's being released soon with Remix v2 (#6887) no longer performs any automatic TS to JS transformations. This issue is a good example of why we've opted to remove this behaviour.
