Update the bundle

Update the bundle based on the acceptable version updates in the Gemfile. Yay semantic versioning.
Update formaggio to v1.3.0

The version and tag are mismatched for now. Once @hab278 fixes NYULibraries/formaggio/issues/12 we'll update again.
Update exlibris-nyu to v2.2.0
Load the figs environment before we require the bundled gems

This change will make environment variables available to gems like exlibris-nyu which need them.
Add the exlibris-nyu environment variables to the Figsfile
Update the rake version

Change the dependency constraint to just contrain major versions of rake.
