Remove vite-plugin-svelte-kit when detected

[JReinhold]

Issue: #19280

What I did

• Remove vite-plugin-svelte-kit when detected as per discussions in [7.0] Incompatible with sveltekit #19280
• Re-enable SvelteKit repros

How to test

• Create the svelte-kit/skeleton-js sandbox
• Ensure that it both runs in dev and it builds

I think you've unintentionally helped me add another feature which I've had in mind, which is allowing users to remove plugins from their vite config by providing a list of names, similar to what Histoire allows: https://histoire.dev/guide/config.html#ignoring-plugins. Having this function will come in handy.

[JReinhold]

Ha great. I just thought that I'd written it 3 times now that it probably deserves it's own utility.

@JReinhold FWIW I think this is a maintenance PR since it touches user-facing code in a significant way. build means it's completely internal to our build system.

@shilman We really need a written guide on those labels soon. 😬

Can someone explain how it should work now ? Previously I've had workaround const plugins = config.plugins.flat(1).filter((p) => p.name !== 'vite-plugin-svelte-kit'); but now it doesn't work on 42 version, and it doesn't build correctly anymore.

None of that should be necessary anymore as Storybook automatically handles that, so hopefully you should be able to delete that.

If you're still experiencing issues with your specific setup I might be easier to reach out on Discord. I'm JReinhold#4884
