az devcenter admin project-catalog | missing examples in reference content

### 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 ...).

### Command list with no examples:

Note: The `az devcenter admin project-catalog` subgroup has nine reference commands and no examples. All other subgroups have at least one example already.
