feat(commands): add descriptions

[alex-courtis]

fixes #2076

I would be most grateful for your review @mrjones2014

I've used the "nvim-tree: " prefix as per the mappings and kept it brief. Most grateful for suggestions...

Many of those descriptions just repeat what the command itself already says. This doesn't add any value really. But frankly I have no idea what else it could say. :)

Descriptions look good. Is there any way you can expose the commands as raw data that we can access directly? Sorta like this: https://github.com/mrjones2014/op.nvim/blob/master/lua/op/commands.lua

That's a great idea. Might be a good opportunity to extract the commands to their own file.

@mrjones2014 I would be most grateful if you tested the new api.get_commands as well as testing each of the commands, to ensure that I didn't miss anything in the refactor.

Would we ever have any more endpoints for commands? If there is a slightest change maybe it warrants nesting like api.commands.get()?

As long as the table structure remains consistent, looks good to me 👍

Much better. Everything is nested now.
