Add support for Obsidian callouts

[jcdiv47]

First of all, thank you so much for the amazing and helpful plugin, now I am able to edit my Obsidian notes in Neovim if I want.

I was wondering if you would consider adding (at least a certain degree of) support for Obsidian callouts, which I don't think the plugin does right now unless I miss something.

> [!info]
> Here's a callout block.
> It supports **Markdown**, [[Internal link|Wikilinks]], and [[Embed files|embeds]]!

Basically what I would like is similar experience as editing a callout in Obsidian:

1. When I type something like > [!info] the line turns into an icon, in similar fashion to say - [x] in checkboxes.

2. When I hit enter/return to go to a new line inside a callout block, it would automatically add > to the beginning of this new line. I presume a simple solution/workaround is some custom comment format options like

vim.api.nvim_create_autocmd("FileType", {
	pattern = "markdown",
	callback = function()
		vim.opt_local.formatoptions:append("r") -- `<CR>` in insert mode
		vim.opt_local.formatoptions:append("o") -- `o` in normal mode
		vim.opt_local.comments = {
			"b:>", 
		}
	end,
})

The plugin is super useful as is right now but I would really like the support for callouts if that is possible and not too much of a hassle. Please kindly let me know if you would consider it. Thanks again!

Hey @jcdiv47, I'm not sure when I'd be able to tackle this, but someone else might. Could you turn this into a feature request issue for greater visibility?

Sure, I'll submit a feature request.
