FES: Simplifying parameter validation messages

[akshay-99]

Most appropriate sub-area of p5.js?

Before starting out with the internationalization for validateParameters in #4616, I felt this needed to be discussed first. So the messages for the FES wrong arguments are still ( kind of ) cryptic in the way they describe the position of the arguments. It says something like parameter #3 (zero-based index), which could be changed to simply to state the ordinal form such as fourth parameter.
This is a very small change but would be nice to have.

The thing is how this would play out with different languages, as they have different ordinal representations. We could use something similar to the locales from numeral.js to display the ordinal short forms (1st, 2nd, 3rd, ...)

Or, since p5 functions don't usually have more than 10 arguments ( not the ones commonly used by beginners at least ), simply having a list of ordinal full forms (first, second, third, ...) for numbers 1 to 10 for all languages in the translation files won't consume much of extra space.

I think that's a great idea but also your point about how it would work language wise can be a problem. I think it would be nice to have a look up in each language of the ordinals to 10th or however many we need as you mentioned, it would be similar to how many localization tools work.
