Update Pikvm from Webui

[soares23]

Hello.

First of all thx for your great work a great project.

Does in the future we have any chance to see on Webui an update Menu or button.

Like to check if pikvm is up to date and if not to update it without commond line?
thx for the reply an have a nice day.

Great, this could even link up with my issue, I'd love to see both ways implemented: #1222

Sup. I'll add this later because updating is an admin task and should require special privileges.

Though this can be done by yaml and script already - at least if there are no proiblems while updating :D
