Pull Request

Purpose

• Changed discords shields.io to a click here button, hopefully to solve the rate limiting issue.
• Changed {! include-markdown "../../../includes/support.md" !} to --8<-- "includes/support.md" to be more consistent with the other pages and less failures depending on where the page is located

Approach

Not that it matters to me, but if you're using cloudflare for this, couldn't you just cache the asset and set a TTL on the image so it updates only every 5m or something rather than just removing it?

I'm not sure what rate limiting issue really is, or what its cause, but it seems like something easily fixed without entirely removing it?

Zak's triage seems likely accurate

I only removed it from the guide pages and kept it on the main page (index) where it also shows the other badges.

I wouldn't know if I can cache the shields, used to work always without issues. The others do, except the discord one.
