Druid ingestion using platform_instance creates a duplicate in the dataset URN

[Rasnar]

Describe the bug
When using the source with druid and with the platform_instance set, the instance platform name is added twice to the final URN.

To Reproduce
Using the datahub cli ingest datahub ingest -c <path to yaml content shown below>.

Using the following recipe:

source:
  type: druid
  config:
    username: ${USER}
    password: ${PASS}
    host_port: ${DRUID_ENDPOINT}
    scheme: druid+https
    env: PROD
    platform_instance: "team1"
    # Ignore internal tables
    schema_pattern:
      deny: ["^(lookup|sysgit|view|sys).*"]
    stateful_ingestion:
      enabled: True # False by default

Let's say that the Druid has a database named druid-metrics, then I get an URN like this:

'urn:li:dataset:(urn:li:dataPlatform:druid,team1.team1.druid-metrics,PROD)'

We can see the team1 entry being set twice in the dataset path.

If I remove the platform_instance, the path is like this, which is correct:

'urn:li:dataset:(urn:li:dataPlatform:druid-metrics,PROD)'

Expected behavior

Based on the example above, the URN should only have the platform_instance once in the name, which would result on something like this:

'urn:li:dataset:(urn:li:dataPlatform:druid,team1.druid-metrics,PROD)'

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):
We are currently using v0.14.1, but I also tested with the CLI v0.15.1 and the result is the same, the platform_instance is added twice to the final URN.

Additional context
Add any other context about the problem here.

In the druid case, the platform_instance is added here:
https://github.com/datahub-project/datahub/blob/master/metadata-ingestion/src/datahub/ingestion/source/sql/druid.py#L54

but maybe it's also added somewhere else on top of this call, but I don't know enough the code to know if this platform_instance is added somewhere else.
