Removed duplicated cn function declaration from lib dir

[damiensedgwick]

This pull request removes duplication of a utility function within the with-supabase example as mentioned in the following issue #73942 - I removed the duplicated code from the utils directory as when shadcn installs a new component, that component will look for the helper function in lib/utils.ts and forcing users to update every component after installation or modify any config files for shadcn seems like a worse DX.

• Fixes Supabase example has duplicate utils for cn.ts #73942

@samcx Hey, here is the pr as discussed. it feels a little wrong leaving an empty lib directory but given the approach of using a Data Access Layer going forward, I think it makes sense. I can always add a placeholder file or README.md in there if we feel like it would be beneficial?

@damiensedgwick Can you make sure to update the path imports? Also seeing an issue with the Tailwind CSS.

You can test this locally with pnpm next-with-deps examples/with-supabase or manually start it up locally with changes via Create Next App.

Fixed the issue with component imports. I actually realised that I removed the wrong instance at first so that has been corrected.

Regarding tailwind, this is a weird error because I have not touched anything Tailwind related but also, the error I am getting

Syntax error: next.js/examples/with-supabase/app/globals.css The border-border class does not exist. If border-border is a custom class, make sure it is defined within a @layer directive.

Does not make sense because the class is within a layer directive as we can see here:

@layer base {
  * {
    @apply border-border;
  }
  body {
    @apply bg-background text-foreground;
  }
}

So I am not entirely sure what you would like me to do here. This is exactly how the css file is setup within every project using shad that I have seen.
