Unhide Section Path, Section Visibility, and Octree hotkeys

I would like to suggest unhiding the hotkeys for the Section Path (F3 + E), Section Visibility (F3 + V), and Octree (F3 + O) debug renderers on Java Edition. Currently, they are hidden behind the "MC_DEBUG_HOTKEY" debug property. To use these hotkeys, you have to start the game with this flag enabled.

However, the settings to toggle these renderers are available in the Debug Options screen (F3 + F6), even if the hotkeys for them are disabled. Since the tools are readily available now, there is no point in disabling their respective hotkeys by default. Having them always enabled could even be helpful to certain content creators, as they would no longer have to use a debug property to get access to them.
