tldr-integration seems to be broken?

I wanted to look up a `jj` cheat sheet and got nothing in return ("Unknown topic...") and was wondering about that, checked tldr repo and saw that there is a cheatsheet available for jj. Then i wanted to search for `jj git` for example, and everything i try searching that contains a space is giving me a 500 error 🫤

Start by reproducing the missing `jj` cheat sheet lookup and the 500 error for searches containing spaces, focusing on the tldr integration and search request path. Done means the available `jj` sheet is returned and multi-word searches such as `jj git` no longer produce a 500 error.
