I have noticed for quite some time that at least for my location (New York time zone, United States), the options for keyboard layout in the installer seem to be missing the Dvorak layout. I found this to be the case up to, and including the recently-released unstable ISO 2.

The available options during installation are the following:

English (US)
English (left handed Dvorak)
English (Programmer Dvorak)
Serbo-Croatian (US)
English (Colemak)

Would it be possible to add English (Dvorak) layout to the list? I think some of the other choices are questionable as well, such as the left-handed Dvorak variant, as well as Serbo-Croatian. If the left-handed variant stays, I think the right-handed variant should be added to complement it, as that only makes sense. Also, I'm aware that there's classic, international, and alternate international variants of Dvorak that could be added, but in the interest of keeping clutter out of the installer, I think they should not be available options in the installer for this region.

I'd suggest the installer look like the following (which also adds the Workman layout), but do what you think makes sense:

English (US)
English (Dvorak)
English (Programmer Dvorak)
English (Colemak)
English (Workman)
