Add which MOK option to choose to the -installation and setup- wiki page

[rotaylo2]

Just installed Fedora KDE Plasma on my Surface pro 7+, and it went very smoothly following the instructions on this page https://github.com/linux-surface/linux-surface/wiki/Installation-and-Setup

However there was one ambiguous point, where I wasn't sure what to do. There is a point where you enroll the secureboot key:

Then, upon reboot, a blue menu should pop up, asking you whether you want to enroll the key. Confirm with ok/yes and when asked for a password enter surface. In case you missed the menu or accidentally chose the wrong options, you can uninstall (fully) and then reinstall the package and reboot to trigger the menu again.

A blue menu did pop up, but it has 4 options, and it is unclear which you should choose - for me they were:

1 continue boot
2 enroll mok
3 enroll Key from disk
4 enroll hash from disk

I had to search around and determined that option 2 was likely the right one (though it could have been option 3?), but it was still kinda nerve wracking. It would be great to which option is correct (for me option 2) and add these to the wiki page.
