Don't register toggle info panel as changed setting

[daniel_m]

Every time the info panel is opened or closed, XYplorer registers that action as a change in settings and turns the "save settings" icon to orange. This happens even when toggling the panel without actually changing anything in it. I assume that toggling the panel is a change in settings because XYplorer has to remember the state (opened/closed) of the info panel.

Could you add an option "Info panel status" to `General > Startup & Exit > Save Settings > Save changes to disk immediately > Apply to` (setting #462)?
