[Enhancement] Option to disable the update notifcations

[Gamerbolts]

Description

Hello! Your new update came through in a message and the server owner was pinged. He asked me to message you and see if you could add an option to disable the update notification on the server. Thanks!

Ok, I will add a switch in the new version to enable and disable notification of new updates to all admins. However, checking for updates is still forced (meaning that you can only remove the notification), as it is good practice to stay up to date. 😆

Very true. ok thanks so much!

To everyone:

Btw, although the latest version has the word 'alpha' written, it can actually be regarded as a complete release version.

It's just that there are still some items in my TODO list, and I want to release a most complete 2.0.0 version.

So feel free to upgrade to MCDC v2! 🤣🥳
