Pulsar Function's cannot reference classes inside NAR file when running Pulsar in standalone mode

**Describe the bug**
If you are running Apache Pulsar in standalone mode, either via a docker image, minikube, or locally and submit a Pulsar Function that references a class that is included in a separate jar file inside the META-INF/bundled-dependencies folder of the NAR file you will get a java.lang.TypeNotPresentException

**To Reproduce**
Steps to reproduce the behavior:
1. Start Pulsar in standalone mode following the instructions here: https://pulsar.apache.org/docs/en/standalone-docker/
2. Download the following NAR [file](https://github.com/david-streamlio/GottaEat/releases/download/v.0.0.1/order-validation-service-1.0.0.nar) and copy it to the /tmp folder inside the docker container using "docker cp"
3. Down the attached function config file and rename it to order-validation-service-config.yml
4. Copy the order-validation-service-config.yml file to the /tmp folder inside the docker container using "docker cp" (https://docs.docker.com/engine/reference/commandline/cp/)
5. Create the Function using the following command:

`/pulsar/bin/pulsar-admin functions create --jar /tmp/order-validation-service-1.0.0.nar --function-config-file /tmp/order-validation-service-config.yml`

6. See error

`ERROR org.apache.pulsar.functions.worker.rest.api.FunctionsImpl - Invalid register Function request @ /gottaeat/services/order-validation-service

java.lang.TypeNotPresentException: Type com.gottaeat.domain.order.FoodOrder not present`

7. Note that the missing class, com.gottaeat.domain.order.FoodOrder, is inside the META-INF/bundled-dependencies/domain-schema-1.0.0.jar artifact inside the NAR

**Expected behavior**
The Pulsar Function should be created and the call to create should complete successfully.

**Additional context**
This had previously worked in prior versions. The

Start by reproducing the failure in standalone mode with the supplied order-validation-service-1.0.0.nar and order-validation-service-config.yml, using the documented pulsar-admin functions create command. Trace the java.lang.TypeNotPresentException for FoodOrder and its loading from META-INF/bundled-dependencies/domain-schema-1.0.0.jar. Done means the function creation completes successfully when the referenced class is packaged in the NAR.
