az functionapp 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.

**Reference command link:** https://learn.microsoft.com/en-us/cli/azure/functionapp/app?view=azure-cli-latest#az-functionapp-app-up

**Current description:** `Deploy to Azure Functions via GitHub actions.`

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