Links to wikipedia are broken

Most appropriate sections of the p5.js website?

Reference

What is your operating system?

Windows

Web browser and version

Firefox (updated) and Chrome (updated)

Actual Behavior

Clicking a link to wikipedia brings me to a broken page.

Expected Behavior

Should arrive at wikipedia page

Steps to reproduce

Go to https://p5js.org/reference/p5.FFT/logAverages/ Click link in description "Octave Bands" Arrive at https://en.wikipedia.org/wiki/Octave_band/, but wikipedia doesn't expect the trailing slash. This same issue happens for all links to wikipedia. I found more by going to https://github.com/processing/p5.js/blob/v1.11.8/lib/addons/p5.sound.js and searching for "wiki"

Would you like to work on the issue?

nope.
