3column-middle label seems to be unrecognized

[izosozi]

Describe the bug

The layout name 3column-middle seems to be unrecognized. The README states:

3Column-Middle

Exactly like 3Column-Left, but the main pane is in the middle, with the other panes on either side. (In previous versions of Amethyst, this layout was known as Middle-Wide.)

and the sample config file includes the comment:

# - middle-wide # The legacy name of "3column-middle"

These imply that middle-wide is not the correct name in the newest stable version of Amethyst (0.21.2), but in fact only middle-wide works as expected, and 3column-middle does not.

To Reproduce

1. Include - 3column-middle in layouts: in the amethyst.yaml file.
2. Create a shortcut for select-3column-middle-layout
3. Reload Amethyst and trigger the shortcut

Expected behavior

The 3Column-Middle layout should be selected

Actual behavior

Nothing happens
