update-metadata doesn't work with code cells in buffer

[benlubas]

Prerequisites

• I am using the latest stable release of Neovim
• I am using the latest version of the plugin

Neovim Version

NVIM v0.9.4 Build type: Release
LuaJIT 2.1.1693350652

system vimrc file: "$VIM/sysinit.vim"

fall-back for $VIM: " /nix/store/xnfdsm9dgfng2spl17m7b7wgfc0yyaa4-neovim-unwrapped-0.9.4/share/nvim "

Neorg setup

{
    load = {
      ["core.defaults"] = {},
    }
}

Actual behavior

:Neorg update-metadata doesn't work when there's a code cell in the file

Expected behavior

it should work

Steps to reproduce

Open a .norg file
:Neorg inject-metadata
add a code block:

@code python
print('hi') # need to load the python TS parser
@end

Potentially conflicting plugins

none

Other information

This is the issue:

neorg/lua/neorg/modules/core/esupports/metagen/module.lua

Lines 282 to 284 in baaf13a

	if tree:lang() ~= "norg_meta" or meta_root then
	return
	end

We're early returning if the first lang isn't correct. But we should probably check all of them.

Help

Yes

Implementation help

I'm fairly sure I know what's going on here. But I'll update this issue if I get smacked by reality.
