[Bug Report] Title of videos is parsed for markdown

### Bug Description

The title of videos that are played are not sanitized when the bot sends the now playing message. This can be used to display markdown text.

Normally the text is bold but this can be removed by adding \*\* before and after the title.

Title is .\*\*I'm not bold\*\*.

Another example with an actual song

This can be used with other markdown styles as well as spoiler tags

### Steps to Reproduce

1. Edit title to have markdown syntax
2. Play the video with the bot

### Expected Result

The characters are displayed and not parsed as markdown.
