psych 4.x breaks libv8 .location.yml deserialisation during extension building

[poloka]

Experiencing similar issue to rubyjs/mini_racer#208 in that the attempt to load the .location.yml. Believe the introduced fix rubyjs/libv8-node@6bbb084 should be the same to update in this library.
https://github.com/rubyjs/libv8/blob/v8.4.255.0/ext/libv8/location.rb#L16

I validated that the file that was attempting to load noted

/Users/gh7199/.rvm/gems/ruby-2.6.6@embedded_content_engine/gems/libv8-3.16.14.19/ext/libv8/.location.yml

Since I am stuck on libv8-3.16.14.19 at the moment, is there a process for releasing a 3.16.14.20 version with the fix as well? I'd branch from a tag and release from the branch but didn't see any branches for each individual major release.
