Add checks for deprecated modules

works for me:
bastelfreak@bastelfreak-nb ~/code/modulesync_config/modules/voxpupuli/puppet-borg $ bundle exec metadata-json-deps metadata.json -v
Checking metadata.json
  saz/ssh (>= 4.0.0 < 9.0.0) matches 8.0.0
  puppetlabs/vcsrepo (>= 2.0.0 < 6.0.0) matches 5.0.0
  puppet/systemd (>= 0.4.0 < 4.0.0) matches 3.5.2
  puppetlabs/stdlib (>= 4.25.1 < 9.0.0) matches 8.1.0
