Cooldown on /[Gamemode] spawn

[Cannafix]

Description

Is your feature request related to a problem?

Kinda, players can use the /[Gamemode] spawn command anywhere (Except while falling if set in config )and get teleported instant

Describe the solution you'd like us to implement.

Add a cooldown option for the /[Gamemode] spawn command in seconds

Describe alternatives you've considered.

Using a cooldown plugin, but would be better if implemented in the plugin

Additional context

Maybe add the cooldown option to the addon config file so each game mode can have different cooldowns? Dont know if anybody gonna use different cooldowns that but you never know
otherwise add the option to the delay section in bentobox config

I plan to use the already existing option in BentoBox's config: island.delay.time.
