Documentation needed for using i18n in layouts and components

[SGarno]

Feature request

Please provide some documentation around using the i18n capabilities within the Layouts and Components. Especially because frameworks like Vuetify also contain an i18n instance and not sure how these should be connected (or not).

What problem does this feature solve?

Demonstrates how to leverage the themeLocaleConfig in vue components for sites that need to customize the ui components not just the content pages.

What does the proposed API look like?

n/a

How should this be implemented in your opinion?

Update the documentation with examples, and preferably one that shows how to use it with Vuetify (or at least how internationalization is recommended to be managed when vuetify is part of the application.

Are you willing to work on this yourself?**

I could update the docs, but not sure what the answer is to be written.
