Error during hiera-eyaml gem installation

[alexeysmovzh]

OS: debian buster 10.6.0
puppetserver version: 6.13.0

On installing hiera-eyaml gem got error (look at commands output below)
I'm don't know anything about ruby gems, but as i understand in newest jruby versions options '--no-rdoc --no-ri' was removed and replaced with '--no-document'.
So gems which are was not updated to new option cause this error.
With option '--no-document' gem was installed successfully.
