Deprecate [HackageDeps] service

[jNullj]

Badge will always return up to date falsely as the upstream site is closed and looking for someone to take over.

The first test if a package exist will always return 200 OK even when non existing as we get the landing page.

Then we will never get "outdated dependencies" as the landing page doesn't include that text.

I looked into the https://hackage.haskell.org/api and couldn't find a quick way to replace the current upstream.

Therefor i propose we remove this badge, this is misleading at best as it's now.
