Missing installation steps in README

[ghost]

We don't document how to install, which leads to confused users.
The steps should be :

• add to pubspec
• flutter pub get
• go to cached folder (nrf_mesh_plugin_<commit_hash> or smth)
• git submodule update --init
• go to android/settings.gradle
• copy script found in the end of plugin's example/android/settings.gradle

Then it's rdy for android compilation. For iOS there is another step

Hello, when I go to cached folder, in windows which for me is this link: ~/AppData/Local/Pub/Cache/hosted/pub.dev/nordic_nrf_mesh-0.13.0

I can't run the git submodule update --init, it says "fatal: not a git repository (or any of the parent directories): .git"
