feat(module): add component-meta:schema hook

[benjamincanac]

This PR adds a component-meta:schema hook to alter the schema before it is being written on disk.

I need this on the Nuxt UI docs as the component-meta.mjs is 13MB (110+ components), by removing the meta.slots[].schema (which I don't need) the file size goes down to 5MB:

import type { NuxtComponentMeta } from 'nuxt-component-meta'

export default defineNuxtConfig({
  hooks: {
    'component-meta:schema': (schema: NuxtComponentMeta) => {
      for (const componentName in schema) {
        const component = schema[componentName]

        if (component?.meta?.slots) {
          for (const slot of component.meta.slots) {
            delete (slot as any).schema
          }
        }
      }
    }
  }
})
