az confluent | missing examples in reference content

### Describe the bug

### Bug category:
**Missing information**

### Request:

The [Azure CLI reference guidelines](https://github.com/Azure/azure-cli/blob/dev/doc/reference_doc_guidelines.md#examples) specifiy at least two examples for each command. Please review the Azure CLI reference guidelines for [examples](https://github.com/Azure/azure-cli/blob/dev/doc/reference_doc_guidelines.md#examples) and [parameters](https://github.com/Azure/azure-cli/blob/dev/doc/reference_doc_guidelines.md#parameters) and add missing content to your source code.

If a parameter accepts JSON content, provide a JSON example in the parameter long or short summary, or in a separate code block.

### Issue summary:
Understanding that not all “create” commands directly generate Microsoft revenue, every “create” or “add” minimally make a revenue-producing Azure resource possible. Consequently, **create commands are the most important examples to add.** Of secondary importance are reference commands with complex parameters (JSON, YAML, URLs, complex Azure resource IDs, multi-valued lists, key:value pairs, conditional parameters, parameter pairs ...).

### Subgroups with no examples:

Note: The commands for these subgroups are in the second table (below). Page views (PVs) for a subgroup are "the sum of all PVs for every autogenerated reference doc in that subgroup." When there is > 1 command in a single GitHub file, the same PV amount is counted for both commands. PVs are being provided as a general idea of customer interest.

| Subgroup name | Status | Command count| 6 month PVs |
|-|-|-|-|
| [az confluent organization api-key](https://docs.microsoft.com/cli/azure/confluent/organization/api-key) | GA | 1 | |
| [az confluent organization environment](https://docs.microsoft.com/cli/azure/confluent/organization/environment) | GA | 1 | 17 |
| [az confluent organization environment cluster](https://docs.microsoft.com/cli/azure/confluent/organization/environment/cluster) | GA | 3 | 10 |
| [az confluent organization environment schema-registry-cluster](https://docs.microsoft.com/cli/azure/confluent/organization/environment/schema-registry-cluster) | GA | 2 | |
| [az confluent organization role-binding](https://docs.microsoft.com/cli/azure/confluent/organization/role-binding) | GA | 1 | 7 |

### Reference commands with no examples:

Note: Some of these command **subgroups** have at least one example. This table is a list of all `az batch` **commands** with no example. PV values repeat when one GitHub file contains > 1 reference command. PVs are being provided as a general idea of customer interest.

| Reference name | Parameter count | is Create | 6 month PVs |
