🚧 [Pages] Create a redirect type of page

🚧 THIS ISSUE IS CURRENTLY A DRAFT 🚧

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

Some pages' URLs can change over time, and if the old link is still used somewhere, you need to keep two copies of that page.

Describe the solution you'd like

Create a new type of page that redirects the user to a URL.
The URL shouldn't be a Text input field but a component similar to the page selector from the header/footer settings to make things as clear as possible.

When the user clicks on Add to add a new page, there should be a dropdown to allow the user to select between Page and Redirect.

The only editable component should be the slug. The page title should not be editable, it should be Redirect: [page to redirect to].

Additional context

A simple Text input URL field would be susceptible to issues over time if the domain or page URL changes.

The Header/Footer page input field is much more reliable in connecting internal & external pages.
