### Error Message

The way the ingest pipeline is configured, we override the `geo.country_name` field with the `location.state` value, which is incorrect for most countries:

For instance the example provided is wrong for France:

https://github.com/elastic/integrations/blob/main/packages/azure/data_stream/signinlogs/sample_event.json#L74-L82

This seems to be the default since the pipeline was created:

https://github.com/elastic/integrations/blob/d7c49618bc21749d67c04d4d058f929a1e5fb696/packages/azure/data_stream/signinlogs/elasticsearch/ingest_pipeline/default.yml#L225-L228

But I don't see the rationale or context behind it.

Is this a limitation caused by the data we get from Azure?
