Onboarding: Remove virtual firehose card (#183929)

As the firehose integration is GA now and includes all relevant
documentation, it's not necessary to have a link to the docs page from
the onboarding flow:
https://www.elastic.co/guide/en/kinesis/current/aws-firehose-setup-guide.html

This PR removes it
