Removed Ruby APIs - Spree Commerce documentation

Code written for an older Spree release, or by a coding agent working from old examples, may call one of these APIs. It fails with a NoMethodError or NameError, and Ruby, the Rails console, RSpec and the Rails log add the replacement below to that error. APIs that still work but print a deprecation warning are not listed here. They are in the upgrade guide for the release that deprecated them.

Removed in Spree 6.0

See the upgrade guide for the reasons behind each change.
