bug(keyBindings): Open/close inspector and Dev Mode keybindings working with Dev Mode disabled

[luisecm]

On MacOS

1. Login with account with Developer Settings hidden
2. Press keybinding for Open/Close Web Inspector
3. Web Inspector is opened even though user has not enabled yet Developer Settings
4. Press keybinding for Open/Close Dev Mode
5. Dev Mode is opened even though user has not enabled yet Developer Settings

@luisecm Do you think we should block all shortcuts if user doesn't enable dev mode?

[luisecm]

@lgmarchi So, as of now we have the following keyboard shortcuts:

• Increase/Decrease Font Size and Hide/Focuse Uplink -> Actions can be performed by any user
• Mute/Unmute microphone/sounds -> This is an experimental feature that is only enabled through Developer Settings
• Open/Close Web Inspector and DevMode -> Both can only be enabled through Developer Settings

For me, the ones that are only enabled through Developer Settings should not be displayed on Settings Keyboard Shortcuts initially, until user enables Dev Settings

I also think that Keyboard Shortcuts should be displayed even for users that have not unlocked Developer Settings

@stavares843 @phillsatellite @InfamousVague What do you think on this?
