[BUG] Misleading documentation on package's allow_downgrade property

General details

Describe the update that needs to be made. Be as specific as possible:

Current docs say that allow_downgrade property is for yum_package resource only, which is not correct.

It was added for apt_package back in 2018: chef/chef@9ee9fac

Many other package resources also have it: https://github.com/search?q=repo%3Achef%2Fchef%20allow_downgrade&type=code

The yum_package resource only note should either be removed completely or replaced with actual supported resources.
