wiki: typo error in presets section

[mufeedcm]

on the wiki,
https://github.com/OXY2DEV/markview.nvim/wiki/Presets#presets-horizontal-rules

here,

local presets = require("markview.presets").horizontal_rules;

require("markview").setup({
    headings = presets.thin
});

it should've been, horizontal_rules instead of headings,

local presets = require("markview.presets").horizontal_rules;

require("markview").setup({
    horizontal_rules = presets.thin
});

The wiki has been rewritten(without the typo).

So, there's no point in merging this.

Ok, but I found another tiny typo. Probably will do a pr later. (I am not in my home). Thanks.
