Config auto generation wrong for ccloud schema registry

**Description**
If you follow the instructions documented [here](https://docs.confluent.io/cloud/current/cp-component/auto-generate-configs.html) for generating config for ccloud, it doesn't correctly pick up the schema regsitry user info config

This line should be changed to `schema.registry.basic.auth.user.info` rather than `basic.auth.user.info` to correctly pick up the config value:
https://github.com/confluentinc/examples/blob/6.2.1-post/utils/ccloud_library.sh#L1195

Open utils/ccloud_library.sh around line 1195 and compare the generated schema registry configuration with the linked Confluent Cloud auto-generation instructions. Reproduce the documented generation flow and verify that the generated configuration uses the schema-registry-specific user-info setting and is picked up correctly.
