az container app up | In in-line help, provide list of azCLI reference commands being executed

### Describe the bug

Customers are asking what Azure CLI reference commands are being executed by our az ... up commands. Doc writers are also requesting this information when they must replicate Azure CLI docs with Azure PowerShell commands. Although the reference list might change based on the parameters being passed, we need clarity in our in-line help and resulting autogenerated reference content.

**Related reference command link:** https://learn.microsoft.com/en-us/cli/azure/containerapp#az-containerapp-up

**Current description of "az container app up":** `Deploy to Azure Container Instances using GitHub Actions.`
**Current description of "az containerapp up":** `Create or update a container app as well as any associated resources (ACR, resource group, container apps environment, GitHub Actions, etc.).`

**REQUEST:** Please modify these descriptions to list each Azure CLI reference command that "up" can/is executing.
