A regression in deprecate_methods was introduced in a982a42:
- Refactoring alias_chain to Module#prepend broke the possibility to deprecate class methods since the module
generated was prepended to the target's instance.
A suggestion to fix this was to use `AS#redefine_method` which would solve the
problem but with the cost of redefining directly the method.
Decided to go with the same alias_chain implementation as before instead.
- Fixes #33253
