Add Git Tag associated with NeMo Docker containers

[awonak]

Please add Git tags associated with the version of code inside the NeMo Docker containers.

https://catalog.ngc.nvidia.com/orgs/nvidia/containers/nemo/tags

For example, there is no obvious connection between the git tags (e.g. r2.0.0rc1) and the Docker tags (e.g. 24.07).

There are times when we need to patch the code inside a NeMo docker container. I would like to be able to clone the NeMo git repo to my local workstation and pin to a tag associated with the specific version of code inside that container so I know that my patch will be compatible with the code inside the container.

Additional context

I reported this issue previously in #11943 and found a workaround, but I still think the request to add Git tags associated with Docker tags would be very helpful and make creating/applying patches much easier.
