Version 7.0 - Need to remove cbdocloader code snippet since it is deprecated from the sample buckets page

https://docs.couchbase.com/server/current/manage/manage-settings/install-sample-buckets.html

The following snippet has to be removed since cbdocloader is deprecated in version 7.0
Install Sample Buckets with the CLI
To install sample buckets with the CLI, use the cbdocloader command. To specify a sample bucket, refer to the bucket’s zip file, which is located in the host platform’s Couchbase Server samples directory. For Linux, this location is /opt/couchbase/samples. The zip file contains the JSON data for the bucket. The command creates a bucket, and installs the JSON data within it. For example:

/opt/couchbase/bin/cbdocloader -c localhost:8091 \
-u Administrator -p password -b testBucket -m 256 \
-d /opt/couchbase/samples/travel-sample.zip
