Support Rendered Preview for reST (Restructued Text) documents

[ashb]

Body

What are you proposing?

Similar to what exists for some docs already, I would love to be able to show a rendered preview of the .rst documents when I'm editing apache/airflow.

For those not in the know, .rst or reST is a documentation format often used in Python projects.

Why does this matter?

For those not in the know, .rst or reST is a documentation format often used in Python projects.

Are there any examples or context?

Screenshots, mockups, workflows, or examples from other tools.

Possible approach

There is https://github.com/elmarco/zed-rst, but it flat out just crashes for me.

I'm not suggesting adding native supoprt for reST (though I wouldn't be against it!) but this feels like something a plugin could/should be able to provide?
