`no-empty-sections` (`MD082`) - option to allow empty section when the next heading is a subheading

[DetachHead]

Problem or motivation

i personally don't consider it an issue for a section to contain no content, when followed by subheadings, because those subheadings should be considered part of the parent heading's content

Proposed solution

an option for no-empty-sections to allow "empty" sections as long as it contains subheadings

Alternatives considered
