Update svgo Babel config

[delawski]

Summary

Since the last version bump of svgo to 2.4.0, a console message is being output on each build:

"extendDefaultPlugins" utility is deprecated.
Use "preset-default" plugin with overrides instead.
For example:
{
  name: 'preset-default',
  params: {
    overrides: {
      // customize plugin options
      convertShapeToPath: {
        convertArcs: true
      },
      // disable plugins
      convertPathData: false
    }
  }
}

This PR fixes the Babel config so that the deprecation notice is no longer rendered.
