docs(plugin): add lazy.nvim install instruction

[technicalpickles]

An alternative to #367 , without listing out all the keys.

[numToStr]

I am looking at this, and it is not clear to me where to put this object. It would be great if you could more instruction to code snippet just like the vim-plug.

And I also don't want to recommend any lazy loading method to load the plugin, as I want to keep the instructions simple and clear. If people wants to lazy load, they can always refer to package manager docs.

I've added a comment to the snippet.

Added lazy = false, but I'm kinda weary of it. I appreciate wanting to keep it simple, but I expect it would be a question lazy.nvim users have about how to best lazily load it, ie if there's an event or keys to add.

[numToStr]

So, you are saying lazy.nvim doesn't have any default mode? Like either you have to lazy load with event, keys etc. or explicitly specify lazy = false to not lazy load.

I don't use lazy.nvim so don't know much about it.

lazy=false is a default value for lazy.nvim, setting it is redundant

This is how I have lazy loaded it BTW. I recommend removing lazy = false from the docs as that makes it very confusing (as if the plugin will break otherwise).

Leaving off lazy = false will do that anyway.

Here is how I AM lazy loading it:

return {
  'numToStr/Comment.nvim',
  event = 'InsertEnter',
  config = function()
    require('Comment').setup({})
  end,
}
