Subject: [PATCH] feat(commands): add tab completion for `:CP open` (#338)

## Problem

`:CP open` accepts `problem`, `contest`, and `standings` but offered no
tab completion for them.

## Solution

Add an `args[2] == 'open'` branch in the `plugin/cp.lua` completer
returning the three valid subcommands.
