Updates href uses for 516 (#88699)

## About The Pull Request

Was just scrolling through the Paradise github since they seem to have
more work done for 516 to see if there's anything I can port over, found
this and thought why not.

Ports parts of https://github.com/ParadiseSS13/Paradise/pull/25105
Specifically, updaing all hrefs to use the internal ``byond://``, and
adding it to grep.

## Why It's Good For The Game

More work towards 516.

## Changelog

Nothing player-facing.
