Array syntax for configPaths

[Tahul]

Is your feature request related to a problem? Please describe.

It would be lovely if configPath key from the configuration supported an array of strings in addition to a single one.

This has no purpose for regular projects, but would be amazing for the ones that uses extends features, such as themes.

Describe the solution you'd like

Keep supporting:

tailwindcss: {
   configPath: '~/my-config-path.ts'
}

But also support:

tailwindcss: {
   configPath: ['~/my-config-path.ts', '~/my-config-other-path.ts']
}

Describe alternatives you've considered

I'm currently using this workaround:

// Import Tailwind config and merge it here.
// Tailwind does not supports supplying multiple config paths.
 nuxt.hook('tailwindcss:config', async (config) => {
   const tailwindConfig = await import('./tailwind.config')
   config = defuArrayFn(config, tailwindConfig)
})
