Update lookup for Hyprland socket location based on changes from commit a5a6480 of hyprland

I tested this locally with Hyprland commit a5a6480.
I am unsure of how you manage breaking changes like this, as this is still only in git and not released.

For those users, I'd recommend checking whether $XDG_RUNTIME_DIR/hypr exists. If yes, use that, if not, use the old /tmp/hypr

I think fallback to /tmp/hypr should be added as there might be cases where you're running the old version of hyprland with the new version of waybar

yep i just updated today to -git branch and ig a fallback should be added also.

[fooeyround]

Yeah, that is a good way to do it. I might be able to add that tonight.

I didn't see this PR existed until I made mine, but I implemented the fallback to /tmp/hypr/ already, so you don't have to do it @JacktheDevel0per :)
