Fixed broken link to bna PDF

This PR solves #129

There is a broken link to the document titled: NEUROSCIENCE- SCIENCE OF THE BRAIN: AN INTRODUCTION FOR YOUNG STUDENTS from British Neuroscience Association European Data Alliance for the Brain.

This had this link previously: https://www.bna.org.uk/static/uploads/resources/BNA_English.pdf. But this returns Access Denied.

This document can be found in the server of another institute, and I have added that link: https://brain.mcmaster.ca/BrainBee/Neuroscience.Science.of.the.Brain.pdf

It is from MacMaster University, and I think this link will be stable. At least for a while.

How do I know it is the same file?

I searched the URL in Google. Click link for performing the same search.

And, in that search, this link of a reading list came up, where the URL matches with the missing file URL.

So, I searched using the title, and the link that I have inserted, came up. Search link
