Allow disabling of scheduled prune

[ryanldy]

Details

This allows us to disable the scheduled command model:prune introduced by this package.

This is needed for cases where we want to add a ->doNotMonitor() (from spatie/laravel-schedule-monitor) to the scheduled command. With this, we will set the config to 'prune_enabled' => false then add the scheduled command model:prune to our own Kernel.php with ->doNotMonitor().

PR Summary 🚀

• Added feature to control email pruning 🌳
  We have introduced a new 'switch' in the filament-email.php configuration file. This switch, called prune_enabled, allows you to decide whether or not a specific cleaning up process (pruning) should take place in managing your emails. When set to true, the pruning will happen.

• Conditional execution of code added 💻🧐
  We've made improvements in a file known as FilamentEmailServiceProvider.php. Now, a particular part of its code will only run if email pruning is enabled (prune_enabled is true). This means the system works smarter, not harder—only doing tasks that are necessary based on your configuration. 🧠✨

So, double-check your settings if you want your unused emails to be trimmed, making sure that prune_enabled is set to true. Keep your project clean and efficient! 😄👍
