Use tasks instead of terminals for the vite process

[skyrpex]

Is there a specific reason for vscode-vite to use a terminal instead of a task? It seems more reasonable to me to use a task, pretty much like other extensions do (ie, prettier, docker, windicss intellisense, etc).

It's a bit confusing to me to see a new terminal process invoked by the extension, specially if I'm able to manually control it.

I could help with a MR if you were willing to change it.

Thanks!
