docs: fix nuxt.config.ts configuration for auto-import components directories

[sadeghbarati]

Resolve #153

If we use the components key in the nuxt.config.ts default config for directories will removed

default configs 👇

{ priority: 1, path: 'D:/Test/nuxt-test/components/islands', island: true },
{ priority: 1, path: 'D:/Test/nuxt-test/components/global', global: true },
{ priority: 1, path: 'D:/Test/nuxt-test/components' },

Instead, it's better to use components:dirs hook for extending auto-import directories

Thanks @sadeghbarati ! Have you tried and verify that using the hook method works? 😁
