fix(cli): lambda hotswap fails if lambda:GetFunctionConfiguration a…

…ction is not allowed (#32301) Closes #32219 ### Reason for this change In SDKv3, the standard `waitUntilFunctionUpdated` function invokes the `GetFunctionConfiguration` API, as opposed to SDKv2, which invoked `GetFunction`. This means that consumers of SDKv3 must allow the `lambda:GetFunctionConfiguration` action in their IAM role policy. ### Description of changes Use a different waiter function provided by the SDK, which invokes `GetFunction` instead of `GetFunctionConfiguration`, and thus restoring required IAM permissions to what they were in SDKv2. See https://github.com/aws/aws-sdk-js-v3/blob/main/clients/client-lambda/src/waiters/waitForFunctionUpdatedV2.ts#L10 > As opposed to https://github.com/aws/aws-sdk-js-v3/blob/main/clients/client-lambda/src/waiters/waitForFunctionUpdated.ts#L13 ### Description of how you validated changes Manul test.
