Move tutorial files out of repo

[tst-ccamp]

Many contributors have difficulty with git lfs. Accordingly, the tutorial files need to be removed from the main earthenterprise repo and will be hosted elsewhere. The goal is to get the size of the repo down small enough that we no longer have to rely on git-lfs.

AC:

1. Tutorial files are removed from the main repo
2. Write follow-on tickets to further reduce the size of the repo and remove git-lfs requirement
