Implement video-message template

[PROger4ever]

Proposal

It'd be great to have a feature to set a video-message template in the settings menu like:

${title}
${link}

When I forward a message from bot to friends, I don't want to have a lot of junk info in it like my username, my nickname, my user id, my token count, video technical info and so on.

Hello @PROger4ever ,

We truly appreciate you taking the time to share your valuable suggestions with us. While it's currently possible to achieve this by manually editing the caption, we understand the convenience of having a default setting. If you're interested, you can modify the default caption template in the ytdlbot/tasks.py file on line 640.
Nonetheless, we will thoughtfully review your input and evaluate the feasibility of implementing these ideas into our project.

Thank you once again for your contribution.
