Hey @UlisesGascon , can you review when available?

This wil be overwritten the next time we pull the automated changes (or when someoen else runs the build step, even without data updates)

To do changes that are not derived from the upstream datasources you must update the custom-types.js file, which is how we set compressible for text/yaml already, in addition to editing db.json.

So, update custom-types to include

'application/yaml': {
  compressible: true
}

Then run the build, without fetching the data again
npm run build
