Add Tweak to disable Microsoft Account Login

[lCTdE]

A suggestion to disable Microsoft Account login for Windows Accounts. The idea behind this is to stop Windows from showing those blocking screens at login and pop-us in the UI that push local account users to switch to a Microsoft Login Account.
At work this is considered a security risk, so normally I disable it using group policy, but for this tweak I decided to use a registry method so those poor souls using Windows 10/11 Home can benefit too.

This is the source I used: https://www.elevenforum.com/t/enable-or-disable-microsoft-accounts-in-windows-11.23799/

In the tweak I used value "1" instead of "3" to avoid possible locks if a Microsoft Account is already in use and because this allows other users to use Microsoft Accounts before applying the tweak.
In the undo tweak part, as I didn't found a way in the tool to delete a registry key like the article suggests, I opted instead to use the value "0". I tested this on a VM and it seems to work.

Comments on the name, order and description of the tweak are welcomed, as I lack a bit of imagination and this is my first time contributing to this tool. I this pull request is denied, I will completely understand it.

I really dislike using group policies as a way to disable features, it feels like a nuclear option.

There's a better option available and there's even an article on ElevenForums for this too:

@SkylerWallace Nice idea, thanks! I will think about it and make a commit with a more mature idea. Right know I'm debating if I should implement only one of them or both and how.

I decided to add the suggested approach as part of the Disable Telemetry Tweak in PR #1832
For my original approach, I'm still not sure if it is still interesting to keep it as a Tweak, move it to Config or just close the PR.
On a second thought, I think my original approach is a "Business Config/Parental Control" kind of thing, so not essential enough for the tool and an easy google search and/or .reg file away, so I'm closing the PR.
