Removing some left over pleroma references

Pleroma is a ActivityPub compatible social media thing. (Think fediverse, mastodon etc.)

• Setup sometime end of 2022 on the office VM

• Removed ~12/06/2024

• The caddy (Reverse proxy) config in the nix config repo still has some references to fed.tardisproject.uk.

• DokuWiki & Netbox still have some references to it.

• The homepage has references to it. Repo

• The wiki entries should be deleted or marked in some way as inactive / deprecated. Do what you think works best

• Netbox will need to be done by an admin. (I don't have perms on netbox and I don't imagine you do either) This has been done To close this we should probably merge two pull requests, one to this repo (NixOS Configs) & the other to the homepage. (See repo above).

If you discover anything else, feel free to remove that aswell.
