[ruby/psych] Introduce `Psych.unsafe_load`
In future versions of Psych, the `load` method will be mostly the same as the `safe_load` method. In other words, the `load` method won't allow arbitrary object deserialization (which can be used to escalate to an RCE). People that need to load *trusted* documents can use the `unsafe_load` method. This commit introduces the `unsafe_load` method so that people can incrementally upgrade. For example, if they try to upgrade to 4.0.0 and something breaks, they can downgrade, audit callsites, change to `safe_load` or `unsafe_load` as required, and then upgrade to 4.0.0 smoothly. https://github.com/ruby/psych/commit/cb50aa8d3f
