Add: Joke module (#53)

* Add: basic joke module

* Add: Core functionality to joke module

* fix: remove random mistype

* Add: Better error handling

* Add: NSFW config flag

* Fix: debug log

* fix!: added suggestions

Now i'm running into an issue where sometimes it fetches the joke perfectly with no issues, but other times i get a `Invalid Form Body` error.

* Fix: Removed undefined errors

I feel so dumb, there was a tiny typo that broke the entire thing, and i forgot to format the response as a string 😭

* Fix: Remove try catch

@zleyyij wanted it so i implemented it
