Update instructions for lucians-luscious-lasagna with datatype

[s-praveen-kumar]

This concept introduces datatypes, both type inference and explicit type annotation is covered. As a beginner I felt really confused as to what type should I annotate my functions with and is it even needed. (I was trying uint and was constantly getting lots of errors). Hence adding a note on the type expectation for future learners.

The introduction has this section:

Bindings are defined using the let keyword. Specifying a binding's type is optional for most bindings, as F#'s type inference can usually infer the type based on their value. A binding looks like this:

Your argument is that this is not enough to go on?

Hi @ErikSchierboom My point was, the learning material introduces both type inference and explicit type annotation. But I was not sure which one to use for the exercise.

At least when I attempted as a beginner, I was annotating different types and was getting error messages.

Makes sense. I don't have much time now, but I'll come back to this!
