docs(migration): state how to register components in content folder as global components

[BayBreezy]

In v2, this was done automatically. It has to be explicitly added in v3.

The issue raised can be found here #2930

📚 Description

While migrating from v2, I noticed that all the components that were once global and could be passed as a string to the <component /> element were no longer being displayed. The components created under components/content were no longer automatically registered as global components.

This PR just adds this note to the migration page so that users know that they have to explicitly mark components within the components/content folder as global.

Aside from hook, the file names can be renamed to include .global.vue suffix, right?

Thanks for the PR. However, this action is not necessary for all users, in your case it is required because you are using these components as dynamic components.

Instead of adding a section, let's add a note in Rendering Components section and notify about changing from global to non-global. And link to Nuxt Custom Components Directories for more details about Nuxt components system.

Yes. You can do that too. For me, there are too many global components to do this.

I made the changes just now.
Removed the section and just added another point under the Rendering Components section.
