Describe the bug

This pattern:

Doesn't match .yaml files nor does it match .yml files. This means that if a file has a .yaml or .yml extension but the language is set to something other than YAML (eg. Ansible), then the formatter won't work since it's not registered to work for that file.

Expected Behavior

Any .yaml or .yml file should be able to be formatted using the formatter.

Current Behavior

Some files that have the .yaml extension but use a different language ID (eg. Ansible) cannot be formatted using the formatter.

Steps to Reproduce

See redhat-developer/vscode-yaml#812
