Subject: [PATCH] Add yaml indent action
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If a line ends with `:` and a user presses Enter, they are probably
defining an object, which requires indentation.

This rule is taken from `monaco-yaml`, but I intend to remove basic
language support there, since that’s already part of `monaco-editor`.
