Allow scaling measurements that are included in recipe instruction steps

[ChrisFhey]

Is your idea or proposal related to a problem? Please describe.
When scaling the ingredient measurements of a recipe, measurements that are included in the recipe instructions are not scaled along, which can cause confusion while cooking.

Describe your idea or proposal
I would like to be able to add measurements in the instruction steps, and have those measurements scale along with the ingredient measurements according to the recipe's scale setting. To make it easier for the app to recognise and scale measurements in the instruction steps, they might be surrounded by braces or similar.

e.g.: Add {320 ml} of milk to a bowl, with scaling set to 2x would be printed as Add 640 ml of milk to a bowl.

I do think it'd be possible to accomplish this even without the curly brace syntax. We have a list of "all" units from unitz-ts, and could parse through and scale anything with a recognized \d+ (M) where M is a list of all known units. The goal there would be that something like "20 minutes" would not be scaled, while "2 cups" would be scaled.

That said, your curly brace syntax proposal would make the task fairly trivial, since very little parsing or edge cases would need to be considered.

Thanks for opening the issue!

Yes, that's exactly why I suggested working with braces or something similar surrounding the measurements to avoid non-measurement units being scaled up as well.

I think it would be fine to incorporate as such, as long as the expected syntax is explained in the project's user guide.
