[Bug]: init fails in React+Vite+npm because of conflicting versions of eslint

[JReinhold]

Describe the bug

When initting Storybook in a fresh Vite+React project with npm, it ends with this from npm, and never continues:

Installing dependencies...

npm WARN ERESOLVE overriding peer dependency
npm WARN While resolving: @typescript-eslint/[email protected]
npm WARN Found: [email protected]
npm WARN node_modules/eslint
npm WARN   dev eslint@"^9.9.0" from the root project
npm WARN   7 more (@eslint-community/eslint-utils, ...)
npm WARN
npm WARN Could not resolve dependency:

npm WARN   @typescript-eslint/utils@"^5.62.0" from [email protected]

npm WARN     @typescript-eslint/utils@"^5.62.0" from [email protected]
npm WARN     node_modules/eslint-plugin-storybook

Indicating that the init failed, but it's "just" npm that never installs any dependencies.

To summarize:

• eslint-plugin-storybook -> @typescript-eslint/utils@"^5.62.0 -> peer eslint@"^6.0.0 || ^7.0.0 || ^8.0.0"
• Found [email protected] in project

I'd expect this to be a problem in any project that uses eslint v9, not just Vite+React.

The root cause of this issue is that eslint-plugin-storybook doesn't actually support ESLint v9, only ESLint v8 which is EOL beginning next week (!).

There is an old PR to support ESLint v9, but there's been no updates in a while: storybookjs/eslint-plugin-storybook#156

Also, when installing npx storybook@latest init, the script looks for .eslintrc, the legacy config format. While still supported in ESLint v9, this config format is deprecated and will be removed in ESLint v10. So this also needs to be fixed.
