Misnamed parameter in containerregistry scopeMaps_list example

On [this](https://github.com/Azure-Samples/azure-sdk-for-js-samples/blob/9447d926dc16c3713b1be71599a385959a5f5bc0/samples/containerregistry/containerregistry_registry_examples.ts#L345C65-L345C77) line, the parameter is named `scopeMapName`, but [the docs](https://learn.microsoft.com/en-us/javascript/api/%40azure/arm-containerregistry/scopemaps?view=azure-node-latest#@azure-arm-containerregistry-scopemaps-list) indicate that the second argument should be a `registryName`.
