Edited readme to include date-fns version

[dado3899]

I changed it so that we are using a previous date-fns version as the solution, I saw a solution by a student that changed the import to:

import {format} from "date-fns";

Which fixes the build step but causes this error on npm start:

Uncaught TypeError: Failed to resolve module specifier "date-fns". Relative references must start with either "/", "./", or "../".

So the fastest solution I found was reverting the npm version but changing the import line is likely the solution we want, I could not get any imports working myself however

I've merged your change for now. I will look into alternatives and update the import statement if needed.
