Feature: Audio embed shortcut

[kryst4line]

Currently you can embed an audio player using HTML code, but I wonder if it's possible to do it using markdown if the link it's an audio file, like for images.

Example:

Instead of writing

<audio controls src="/media/original/cff449e4-5982-4e02-b936-1e77be0a7082.mp3"></audio>

it would be much simpler to use

![alt text](/media/original/cff449e4-5982-4e02-b936-1e77be0a7082.mp3)

markdown to html conversion is implemented in utils.py method
def markdown_to_html(markdown_text: str)
It seems that python markdown lib does not natively support this, but extension can be made through their Extensions API.
It seems it's not implemented through Third Party libs either.

Might be a fun thing to implement!
