add a language filter to the GFI list #258

So uh, I'm trying to do this at the moment, and successfully managing to filter the issues returned from the DB based on a language parameter. I felt doing it this way instead of handling it all in the frontend would mean that paging still worked?

BUT I haven't a clue how to get the front end done. I want to have a drop down select list and use the existing pattern of using htmx to fetch new data from an endpoint and the replace the list with the new data, but it looks like I need a "fragment" / partial code block for this? Or am I looking too much into it and it's actually easier to implement than I think 🙈
