Link to 'stable' documentation is broken

[alhirzel]

The link to 'stable' documentation on the README points to: https://juliaclimate.github.io/ClimateSatellite.jl/stable/

This URL is a 404 as of right now.

Hi! Thanks for checking out the package. Use the dev/ version of the documentation first. I need to set up GitHub token access etc. before the stable version will work.
