Update documentation: ivy-toggle-fuzzy is no more the keybinding

[neojski]

Vaguely related to #1213.

I also wanted to point out that having to modify 3 places in the docs suggest that there's too much duplication. I'm not actually sure what's the difference between ivy-help.org and ivy.org and ivy.texi.

Thanks.

I'm not actually sure what's the difference between ivy-help.org and ivy.org and ivy.texi.

ivy.texi is generated from ivy.org. Why is it in the repo then, if it's generated? MELPA will detect it and build ivy.info from ivy.texi.

ivy.org is the main doc.

ivy-help.org is the inline doc. You can access it with the binding for describe-mode when ivy is active, e.g. <f1> m or C-h m.
