Add link to my learning repo

[JordanMartinez]

I propose adding a link to my learning repo here since it (currently) has more up-to-date documentation than a number of other materials.

Any comments on this?

I think https://github.com/purescript/documentation is the better place for that link, that way we have a single place to collaborate/coordinate on keeping our resources up-to-date.

I've opened an issue there.
