Update ventoy version automaticly over internet

[crasadure]

Hi @ventoy
With the ventoy Update button in the ventoy2disk.exe file, we can manually update our current system to a higher version.

How about we make the update process automatically update Ventoy to a higher version by putting an Auto Update button on the interface?

When a new version of Ventoy comes out, it should ask the user if you want to update to the new version. When the Update button is pressed, the system will automatically update the VTOYEFI section over the internet in the background.

In this way, those who want can update their system manually, and those who want can update it automatically over the internet.
