Description

Symfony can already automatically generate a text version of an e-mail in \Symfony\Bridge\Twig\Mime\BodyRenderer using league/html-to-markdown (see https://symfony.com/doc/current/mailer.html#text-content)

But there is no way to configure the conversion options (e.g. we would like to remove the img tags as well). The instantiation is hardcoded in the constructor and the BodyRenderer itself is marked as final:

(The only way I see as an extension option is to copy the BodyRenderer to MyBodyRenderer, modify it and try to keep up with the changes in Symfony)

I suggest that the League\HTMLToMarkdown\HtmlConverter is wrapped behind some HtmlToTextConverter interface, so it would be possible to either replace it with other convertor or at least configure it differently.
