Description

I'm trying to use prophet cross_validation but I received a value error for unrecognized type when I try:

df_cv = cross_validation(m, initial='120 months', period='12 months', horizon = '12 months')

I think the error should return a list of valid types so that I don't have to go look up why months aren't recognized as a valid unit.

Contributor guide

Research direction
Locate the cross validation function in the prophet codebase and find where the error for unrecognized unit type is raised. Update the error message to include a list of valid unit types.
