No-Index Markup in discord invite's X-Robot tags

[MillionBlossoms]

Description

In a follow-up from this issue that was temporarily fixed in 2023, #6180, some invites from discoverable servers once again have the no-index markup applied to them, causing server invites to disappear from Google as search engines are blocked from crawling invite links.

Steps to Reproduce

Discord staff can check X-Robot tags in discord invite links. Here is one example from Google's Rich Results Test: https://search.google.com/test/rich-results/result?id=O17zQLFwK9nYHCfAZTj9eQ

Expected Behavior

All invites to discoverable servers could/were eligible to be indexed until now.

Current Behavior

Many discoverable server invite links are not indexable.

Client and System Information

Applies to all search engines.

This server is not discoverable, as you can see by the missing DISCOVERABLE feature on the API: https://discord.com/api/invite/democrats

Testing with another discoverable server, the noindex meta tag is correctly removed: https://search.google.com/test/rich-results/result?id=RCKWmOKu8BYod2XqdkFjbg
(this server has the DISCOVERABLE feature: https://discord.com/api/invite/discord-developers)
