Fix grammar in documentation section

[HonkingGoose]

This is a 🔦 documentation change.

Summary

Change the word 'is' to 'are', because when the subject is plural, we use 'are'.

Context

Thank you for catching and correcting the issue, @HonkingGoose.
For future reference, I recommend providing a short and meaningful commit message for the sake of our Git History.

@ashmaroli I agree that a good commit message is important! I was not sure what the right commit message should be for one-word changes such as this...

Something like:

"Fix grammar in documentation"

Or:

"Fix grammar, change word "is" to "are"

Or:

"Change word from "is" to "are"

What would you prefer in future?

I believe "Fix grammar in documentation" summarizes the type of change and the area of code being changed, perfectly — The change is not in one of the lib/ files, or test/ files..
