Python dependency is abstruse

[smaddock]

The only way I could get the macadmins/python 3.9.1 requirement met was:

• build the macadmins/python repo
• copy the recommended/payload/Library/ManagedFrameworks directory into nudge-python’s payload/Library directory
• build nudge-python 2.0.1 with munkipkg

Most people will not be able to figure this out without it being clearly documented, and conversations on MacAdmins suggest others are running into this issue as well. A modification to the build process to include the above would be beneficial.
