use YAML.unsafe_load in Psych 4.x (Ruby 3.1+)

Psych 4.x defaults to "nanny mode" to handle untrusted data.
This causes breakage with since YAML references (aliases)
emitted by dtas-player can't be handled by Psych clients under
Ruby 3.1.  Since dtas is single user and is a shell designed to
run arbitrary code, favor the new YAML.unsafe_load API which
behaves like the old YAML.load in Ruby <= 3.0.
