Remove the old implementation of the Caps lock button

The previous implementation has unintended interactions with
auto-capitalisation.

Caps lock can now be locked twice at the same time, independently:
- Long press on shift
- Tap on Caps lock

Both have to be disabled independently. This might seem weird.

 ## Building the app
 
-The application doesn't use Gradle and it might be hard to use some features of
-Android Studio.
-
-Fortunately, there's not many dependencies:
-- OpenJDK 8
+The application uses Gradle and can be used with Android Studio, but using
+Android Studio is not required. The build dependencies are:
+- OpenJDK 17
 - Android SDK: build tools (minimum `28.0.1`), platform `30`
-- Make sure to have the `$ANDROID_HOME` environment variable set.
+
+Python 3 is required to update generated files but not to build the app.
+
+For Android Studio users, no more setup is needed.
 
 For Nix users, the right environment can be obtained with `nix-shell ./shell.nix`.
 Instructions to install Nix are [here](https://nixos.wiki/wiki/Nix_Installation_Guide).
 
+If you don't use Android Studio or Nix, you have to inform Gradle about the
+location of your Android SDK by either:
+- Setting the `ANDROID_HOME` environment variable to point to the android sdk or
+- Creating the file `local.properties` and writing
+  `sdk.dir=<location_of_android_home>` into it.
+
 Building the debug apk:
 
 ```sh
-make

-If the build succeed, the debug apk is located in `_build/juloo.keyboard2.debug.apk`.
+Nix users can call gradle directly: `gradle assembleDebug`.

-It's possible to save the local debug.keystore into a github secret, so the same keystore is utilized to build the debug apk in the CI github actions.
-Doing this, they wil have the same signature, thus the debug apk can be updated without having to uninstall it first.

-
-```sh
-cd _build
-gpg -c --armor --pinentry-mode loopback --passphrase debug0 --yes "debug.keystore"

-A file will be generated inside the local `_build/` folder, called `debug.keystore.asc`

-You can copy the content of this file, and with that, paste it into a new github secret in your repo settings.
