Ruby 3.1 compatibility

[sphynx79]

The new ruby 3.1 use as default gem psych 4.0.3, with this version there is problem to load alias, i receive this error message
Unknown alias: defaults
To fix the problem you can change your yaml_to_hash method in this way:

    # Internal: Parses a yml file that can optionally use ERB templating.
    def yaml_to_hash(file_name)
      return {} if (content = File.open(file_name).read).empty?
      if Psych::VERSION > '4.0'
        YAML.load(ERB.new(content).result, aliases: true).to_hash
      else
        YAML.load(ERB.new(content).result).to_hash
      end
    end

In this way it works with ruby 3.1 and keep backwards compatibility

@sphynx79 Released a fix under better_settings-1.0.2, which now requires Ruby 3.1 or greater.
