Kirbytags:after and extra paragraph tags

In principle, it’s no more than doing this (installing with composer)

plugins/test/index.php

<?php 
@include_once __DIR__ . '/vendor/autoload.php';

use Michelf\Markdown;
Kirby::plugin('texnixe/test', [
    
  
    'components' => [
        'markdown' => function (Kirby $kirby, string $text = null, array $options = [], bool $inline = false) {
            return  Markdown::defaultTransform($text);
        }
    ]
]);
