v0.5.1

Hotfixes

• Increased the minimum required @ansible/ansible-language-server
  version to 0.2.5. It has added a guard for linting only playbook
  files with the Ansible's built-in syntax-check when ansible-lint
  is unavailable. This is used for providing the diagnostics
  information to the client (VS Code editor instance) (#259)
