az containerapp | 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 containerapp add-on](https://docs.microsoft.com/cli/azure/containerapp/add-on) | Preview | 1 | 541 |
| [az containerapp add-on kafka](https://docs.microsoft.com/cli/azure/containerapp/add-on/kafka) | Preview | 2 | 132 |
| [az containerapp add-on mariadb](https://docs.microsoft.com/cli/azure/containerapp/add-on/mariadb) | Preview | 2 | 86 |

| [az containerapp add-on qdrant](https://docs.microsoft.com/cli/azure/containerapp/add-on/qdrant) | Preview | 2 | 93 |

| [az containerapp add-on weaviate](https://docs.microsoft.com/cli/azure/containerapp/add-on/weaviate) | Preview | 2 | 84 |
| [az containerapp ssl](https://docs.microsoft.com/cli/azure/containerapp/ssl) | GA | 1 | 287 |

**NOTE:** Azure CLI command [az containerapp ssl](https://docs.microsoft.com/cli/azure/containerapp/ssl) is a Core command and needs to be fixed in Azure/azure-cli.

### 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.
