[FEATURE] Feel free to copy my PR about the improvement of the `bilibili` shortcode I submitted to DoIt theme

[CXwudi]

Describe the feature you want

Recently, I submitted a PR to one of the forks of the LoveIt theme called DoIt. In that PR, I made the bilibili shortcode more configurable and disabled autoplay by default.

The PR is at HEIGE-PCloud/DoIt#1250.

I am submitting this issue just to grant you, the author of this theme, to copy and adapt my code into this beautiful theme.
