Visual Editor should add `Visual` format to diff revision option to switch dropdown
== Feature Summary ==
On the current experience, a user is able to use different `diff` formats:
- [[ https://en.wikipedia.org/w/index.php?title=Kansas_City_Chiefs&diff=1140635757&oldid=1140634209&diffmode=visual | Visual ]] when VE is installed (URL param `diffmode=visual`)
The VE extension should add `Visual` option to diff revision switch dropdown so that users can easily switch between the different available formats.
== Use Cases ==
As a viewer, I am able to switch between different diff formats.
The drop down should display the options according to installation.
Fresh install with VE enabled and without Wikidiff2 options:
"Visual", "Two columns"
