fix(ergol-kanata): CapsLock-related bugs

Fix bugs on some keys when CapsLock is enabled by using the `unicode`
function throughout, instead of aliasing keys from the base layout.

This also increases portability to non-AZERTY system keymaps, as the
non-base layers are now completely keymap-agnostic.

NB The `unicode` function works with the parenthesis and double quote
characters only starting with Kanata 1.7.0.

 An Ergo-L "portable" driver, emulated with Kanata over your regular keymap.
 
+## Prerequisites
+
+Kanata v1.7.0+ is required.
+
 ## Caveats
 
 - Only Windows is supported at this point; this *doesn’t work* on GNU/Linux
   (yet?) and is untested on macOS.
 - Only Azerty-FR is supported as the base keymap at this point.
 - Mac keyboards are not supported at this point.
-- CapsLock can have unexpected behaviour, please report bugs.
 - Not all the dead keys on the AltGr-Shift layer are implemented yet.
 - Some other exotic characters may be missing, please report bugs.
 - Layer taps are not supported at this point.
