Test Scrolling and Folding API commands within VSCodeVim

[rebornix]

As VSCodeVim is doing differently as Vim example, I'd like to test against latest VSCode Vim bits as well, all test scenarios are the same as #11127. The only difference is the setup steps

• any OS @alexandrudiam
• Clone the repository VSCodeVim
• Install dependencies by following https://github.com/VSCodeVim/Vim/blob/master/.github/CONTRIBUTING.md#first-time-setup
• Open VS Code on VSCodeVim
• Run the extension using Launch Extension.

Complexity 4 as well.

Basically it appears to me that out of that list the following work correctly:

• z + z
• z + c (without counts)
• z + o (without counts)
