Parameters missing from README.md

[llowder]

This was noted in version 4.0.0, and is still an issue in master.

In the README, in one of the examples it mentions some hiera-eyaml-gpg related in one of the examples, but these options are missing in the parameter reference section.

Looks like at a minimum, these are all missing:

  $eyaml_gpg_name                           = 'hiera-eyaml-gpg',
  $eyaml_gpg_version                        = undef,
  $eyaml_gpg_source                         = undef,
  $eyaml_gpg                                = false,
  $eyaml_gpg_recipients                     = undef,
  $eyaml_pkcs7_private_key                  = undef,
  $eyaml_pkcs7_public_key                   = undef,
  $ruby_gpg_name                            = 'ruby_gpg',
  $ruby_gpg_version                         = undef,
  $ruby_gpg_source                          = undef,
