Display controls line of status-bar plugin if pane size=1

[welcoMattic]

Ref #1864

This PR will display only the controls line of status bar plugin if its pane has size=1 instead of tip line.

The tip line is still displayed if size=2.

(FYI: it's my 1st PR on a Rust project, if it miss something let me know)

Hey @welcoMattic - looking great! Thanks for choosing us for your first Rust PR :)

I left a minor comment in the code. Otherwise, I think I'd rather not add another default layout for this so they won't get too crowded. We've now changed the plugin so it "does the right thing" if someone chooses to create such a layout.

After these changes, I'd be happy to merge.

Let's change this to rows - it was previously prefixed with an underscore to denote that it's an unused variable in this function. Now we use it.

@imsnif Thanks for your review. I addressed your comments, I hope it's now ok for you ;)

@welcoMattic does this still work for you?

I've tried this today with zellij 0.34.4.
I'd love to only see the keybind hints, not the tips, but if I set size=1 I don't get a status-bar at all anymore. With size=2, it works as normal.

Here is my layout:

layout {
    pane size=1 borderless=true {
        plugin location="zellij:tab-bar"
    }
    pane {
        pane 
    }
    pane size=1 borderless=true {
        plugin location="zellij:status-bar"
    }
}

@panki27 you are right, since last version it's broken. Can you open a new issue please?
