Select snacks picker element based on cursor position

[YosefBayoude]

When calling snacks picker, auto select the corresponding item, based on the cursor position on the buffer.
It's a small QOL imrpovement, that doesn't have much impact on usability, but provides quick info at a glance.

I'd prefer to do this the way we do for telescope, where we determine the selected index while iterating over symbols to build the list

aerial.nvim/lua/telescope/_extensions/aerial.lua

Lines 183 to 189 in 9ebc135

	local position = bufdata.positions[bufdata.last_win]
	for _, item in bufdata:iter({ skip_hidden = false }) do
	table.insert(results, item)
	if item == position.closest_symbol then
	default_selection_index = #results
	end
	end

Made the requested changes, let me know what you think. Do note tho, setting the cursor happens on the on_show() call. Looking at the documentation and the code examples, I haven't found a way to set it at picker creation like Telescope does it. Any comment / information would ge helpful.

Great, LGTM! Looks like one legit CI failure, the others should go away if you rebase master

Oops, I'm not sure, I think my force push after the rebase messed up the flow 😅, could you please review again ? ty

@YosefBayoude it looks like you have a small type error as well as a formatting problem (just in case you didn't see the tests failed)

[YosefBayoude]

Yes I did see it, haven't had time tho, will look into it over this weekend

[YosefBayoude]

Could you please rerun the workflow to see if it conforms now ? Thanks

[stevearc]

LGTM thanks for the PR!
