[Guide] Self-hosting a Lemmy server with Podman

Hey everyone! I run a server with Podman instead of Docker (and on an arm64 processor), so when I wanted to host a Lemmy instance on it, I faced a bit of challenges. I ended up writing this guide so if anyone else is in the same pickle, this should make installing Lemmy closer to headache-free.
If you're reading this post that means the guide works!
