Add Option to control when Plugin triggers Restart (on add & delete not on Change)

[Kingju777]

Clear and concise description of the problem

I wish to restart the server only when a file is added or deleted not, when someone makes a change in the file.
When a file is added or deleted i need to do some Housekeeping to make my Application work.
And to trigger that i need to restart the Server.

restarting the server on change is just distracting for me, because it takes to long and repaints the screen a second timer

Suggested solution

please Add an additional Option that globally controls what is watched

updateOn?: "all"|"AddDelete"

more generally

updateOn?: {
    add:boolean,
    change:boolean,
    delete:boolean,// Vite calls this "unlink" and not delete
}

if you want i can implement the Change in your preferred way and open a PR.

Alternative

i can completely understand if this request is out of scope for this projekt.

Additional context

thank you very much for creating and maintaining this awesome Plugin.

Hi @antfu, I know you will be very busy. It'll be really helpful if you add this option. So we can provide an event type to trigger restart/reload the vite server. Thank you so much for all your work, please keep up the same.
