feat: transformers translation example in model-hub [DET-5633]

[liamcli]

Description

Add huggingface transformer's translation example to our model-hub.

Test Plan

• [x] Train each experiment configuration and confirm performance is as expected

Commentary (optional)

The upstream transformers translation example has configurations for three model types: marian, t5, and mbart. The marian and mbart configurations errored out when I trained to run it myself outside of determined.

The example configurations provided in this PR fix those issues.

• [x] Release notes should be added as a separate file under docs/release-notes/. See Release Note for details.
