INSTALLING.MD misses some dependencies
To install the dependencies, the guide says:
> Install dependencies. During installation, use default=all by leaving the input blank and pressing enter.
> 64-bit: `pacman -S mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake git`
> 32-bit: `pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake git`

And then it says to install JDK 21,
> On all platforms, install Java JDK 21:
> ```
> curl -s "https://get.sdkman.io" | bash
> sdk install java 21.0.2.fx-librca
> ```

But it seems like that script requires `unzip` and `zip` packages to be installed on the system. So it would be better if we just add those packages to the dependency installation section in the `installing.md`.

How to reproduce:
1. Install MSYS2 (Windows) freshly
2. Do not install any packages, only execute the commands listed in the `installing.md`.
3. When executing the SDK installer script, it will fail saying that `Please install unzip on your system ...`
