Rendering markdown in documentation

[juanlopez4691]

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

Documentation markdown for autocompletion options doesn't render correctly. E.g.

Those are samples of PHP code (from a WordPress project and from a Laravel file)

I am using a configuration based on LazyVim.
I also tried with just the default config for blink.cmp (no customizations at all) and got the same results.

Relevant configuration

No response

neovim version

NVIM v0.10.3

blink.cmp version: branch, tag, or commit

v0.9.2 (commit e3b7cb4)

Do me a favor and send the output of vim.print(item) at this position: https://github.com/Saghen/blink.cmp/blob/main/lua/blink/cmp/completion/windows/documentation.lua#L64

@Saghen This is what got (a couple of samples):

        line = 85
      },
      start = {
        character = 7,
        line = 85

The difference is that\nHTML will be displayed to the user. It is recommended to use this function\nonly when the execution should not continue any further. It is not recommended\nto call this function very often, and try to handle as many errors as possible\nsilently or more gracefully.\n\nAs a shorthand, the desired HTTP response code may be passed as an integer to\nthe `$title` parameter (the default title would apply) or the `$args` parameter.\n\n_@param_ `string|WP_Error $message`  \nOptional.
