Allow scaling measurements that are included in recipe instruction steps about recipesage

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.
