Link to "A Mathematician's Lament" short story is broken

[SynapticRewrite]

Super minor issue, in the second paragraph of the "How to Learn Deep Learning" section of 01_intro.ipynb, the link to the short story is broken, but a quick search turns it up both from the original MAA site as well as from the Internet Archive.

Old broken link in notebook: https://maa.org/external_archive/devlin/LockhartsLament.pdf

New MAA link: https://maa.org/sites/default/files/pdf/devlin/LockhartsLament.pdf
Internet Archive option: https://archive.org/details/pdfy-yhvz8YJgZp2hkjv3
