feat(commands): implement :CP open [problem|contest|standings] (#319)

Browse source 
## Problem

There was no way to open a problem, contest, or standings page in the
browser from within the plugin.

## Solution

Add `contest_url` and `standings_url` to `MetadataResult` and persist
them in the cache. Add `cache.get_open_urls` to resolve all three URLs.
Wire up `:CP open [problem|contest|standings]` in `commands/init.lua`
to call `vim.ui.open`, warning when a URL is unavailable (e.g. CSES
has no standings). Closes #315.
