Add development checklist item for ensuring recipe descriptions are sufficient

### What problem does your feature request solve?

New recipes don't always have sufficient detail in their descriptions and reviews are not catching that.

### Describe the solution you'd like

Add development checklist item for ensuring recipe descriptions are sufficient.

New bullet point around scientific review, specifically mentioning recipe description. Reviews should make a judgement call over what can be referenced back to the original paper, etc., verses what needs to be described in the description itself.

### Describe alternatives you've considered

Locate the development checklist referenced in the issue and read nearby review guidance before editing. Add a scientific-review checklist item covering whether recipe descriptions provide enough detail or can appropriately refer back to the original paper. Done means the checklist clearly prompts reviewers to make that judgement.
