Add pagination SEO link tags

[Zach-Jaensch]

Apologies in advance if I have missed something in the contributing process.

Fixes #52925

What?

Adds metadata config option for pagination link tags.

Why?

The <link rel="prev" and <link rel="next" are used by search crawlers and can help with SEO performance.
For more information: https://developers.google.com/search/blog/2011/09/pagination-with-relnext-and-relprev

How?

Uses existing patterns for metadata config.
