feat(mapbox): update to mapbox api v6

[Mathieu-R]

This changes aim to update the mapbox geocoder to the API v6.
In particular, it allows us to retrieve informations about the confidence level of the geocoding that we put in the extra field of the return formatted object.

...
extra: {
  id,
  bbox: properties.bbox ?? undefined,
  confidence: properties.match_code ? isTrustableMapboxResult(properties.match_code) : 0
}

Note we do not have informations about the category in the extra field since it is related to POI and these have been seperated from the Geocoding API. They are now part of the Search Box API and it will also be soon deprecated from the v5 Geocoding API (see Geocoding v5 POI deprecation: https://docs.mapbox.com/api/search/geocoding-v5/).
I guess anyway that POI is not relevant to geocoding so it makes sense to not have this category property in the returned object.

Hi @Mathieu-R, Thanks for your PR, which is highly appreciated. Can you please check on the failing tests?

Yes, it is fixed.

Can you please move this to src/geocoder/mapbox.js as this is a function solely for the mapbox geocoder.
Would you also mind, removing the console.log() statment?

[Mathieu-R]

Yes sure
