Include Update Button for Script in WebUI

[ExtremeFiretop]

Hi @Martinski4GitHub

As requested by @TheS1R and vlord here: https://www.snbforums.com/threads/merlinau-v1-4-4-the-ultimate-firmware-auto-updater-webui-gnuton-support.91326/post-948545

I am implementing a check for updates from the WebUI functionality.

Here is the general flow:

• Script update pushed out but not yet detected by nightly cron:
  

• clicks check for updates button, and confirms to check for updates:
  

• Update found and prompting in the WebUI of an available update:
  

• User confirms to install the update now with the checkbox:
  

• Update completed, prompt is now gone:

Nice implementation!!

P.S.
Yesterday, Saturday evening, my wife and I went out for dinner to celebrate Mother's Day; and today we'll have a family gathering for Mother's Day with my parents, my in-laws, my brother's family, and other relatives, so I'll be offline most of the afternoon and evening. Hence, I'm reviewing this PR now while I have some time. Just FYI.
