Equivalent rule for Redirector extension:

Reddit redirect

• Example URL: https://www.reddit.com/example
• Include pattern: ^https?://www\.reddit\.com(?!/(?:(?:media|gallery|settings)\b|r/\w+/s/))([/#?].*)?$
• Redirect to: https://old.reddit.com$1
• Pattern type: Regular Expression
• Description: Old Reddit Redirect

Both of these methods are faster than using window.location.replace in Greasemonkey, which requires an additional network request even with @run-at document-start.

how do you install it though ?

To install, open the raw link and follow the prompt on the Userscripts extension modal. Alternatively, you can create a new JavaScript item on the extension page and copy/paste the script. On iOS, go to the same link and tap the puzzle icon in the address bar and then the “Userscripts” menu item. Instructions to install the Userscripts extension can be found here.
