Add option to `hyprctl rollinglog` to follow the Hyprland logs

[zjeffer]

Description

Right now, to follow the current logs, I run tail -f $XDG_RUNTIME_DIR/hypr/<id>/hyprland.log. I notice hyprctl rollinglog is able to show the last 50-ish lines, but not able to follow the logs.

Proposal: add a parameter (-f, --follow) to hyprctl rollinglog that follows the output similar to tail -f <file>.

Got it! Working as proposed, for every amount of followers.
Now i have to read all stuff (local contributing guides, code style, etc)

Honestly I'd be in favor of rollinglog follow by default, and optionally have a tail flag if someone has an use for it.
From the name I'd expect rolling log to be rolling, so that seems more intuitive for me.

@tchofy I think similarly, but as for me it is more correct to preserve the existing behavior(it is my first PR here).

@zjeffer i think issue can be closed as for now
