ergodox: Update algernon's layout to v1.11

Overall changes
===============

* Updated to work with QMK master.
* The `$` and `^` symbols on the number row were swapped on both the base and
  the ADORE layers.
* The bracket tap-dance keys can now be used to input Japanese brackets, `「`
  and `」` with a third tap.
* The second column of the top row on the right side will act as a "Social"
  application selector on the `AppSel` layer.
* The third key on the same column will select a password manager.
* The `GUI` key will now launch `rofi` when triple-tapped.

Miscellaneous
=============

* The `👶` symbol can be entered with UCIS.
* The `👪` symbol can be entered with UCIS.

Tools
=====

* `tools/hid-commands` can now find the `Mstdn`, not just `Slack`, as the
  "Slack"/chat app.
* `tools/hid-commands` can now find the Plex web app as a music/media player.
* `tools/hid-commands` now understands the "Social" application selector. It
  raises the `Mstdn` and `Tweetdeck` windows, but keeps focus on the previous
  window.
* `tools/hid-commands` now understands the "Social2" application selector, which
  raises `Signal` and `Viber`, but keeps focus on the previous window.
* `tools/hid-commands` is now able to select a password manager (KeePass*).
* `tools/hid-commands` can now run `rofi` when receiving an `appsel_helper`
  command (triggered by a triple-tapped `GUI` key).
