YAML parser doesn't process valid YAML

[Reinier Kaper]

Reporting a bug?

The following code throws an error in webpack, even though this is totally valid YAML.
It's making it difficult to move translations into their own yaml files because of this issue.

en:
  'some-key': 'bar'

Error:

Module parse failed: Unexpected token (2:5)           friendly-errors 12:41:58
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| en:
>   'some-key': 'bar'
|

### Expected behavior

Valid YAML to be parsed
