Description

Using Gatsby v5, when you try to import a yaml file, you get an error from the yaml-loader.

Reproduction Link

https://github.com/pettinarip/gatsby-5-yaml

Steps to Reproduce

1. Create a yaml file in the project
2. Import it from a page component (import yamlFile from './test.yaml')
3. Run gatsby develop
4. See error

Expected Result

gatsby-develop runs without any error when you try to import a yaml file

Note: I've tried doing this but it didn't work.

exports.onCreateWebpackConfig = ({ loaders, actions }) => {
  actions.setWebpackConfig({
    module: {
      rules: [
        {
          test: /\.ya?ml$/,
          type: `json`,
          use: [loaders.yaml({ asJSON: true })],
        },
      ],
    },
  })
}

Actual Result

ERROR UNKNOWN
