fix(cli): remix detection (#4972)

# What

Some remix templates doesn't package a `vite.config.*` file at their root.
It's the case for the recommended starter "stack" templates: blues-stack, indie-stack and grunge-stack.
As recommended in a TODO comment, it's more suitable to check for a `@remix-run/*` dependency in the package dependencies.

# How

- decouple vite and remix checks
- retrieve the `package.json`
- allow passing a `cwd` to the retrieval method
- remove the "empty config file list" that can be empty for a remix stack
- check that the `package.json` contains a `@remix-run/*` dependency

# Test

Added a fixture by running `npx create-remix@latest --template remix-run/indie-stack` in the [frameworks](/Fluf22/shadcn-ui/tree/fix/cli-remix-detection/packages/cli/test/fixtures/frameworks) folder and named it `remix-indie-stack`, if ever we want another stack as a fixture later
