Current multilang-support and espnet-tts services incompatible with CUDA 12.8

[aidanbruneel]

Summary

@Miliya-Ai discovered that the Docker containers need to be updated to work with CUDA 12.8:

@jeffbl I think we could try changing ARG CUDA="11.8" to ARG CUDA="12.8" in services/multilang-support/Dockerfile, based on the information in the link. However, since I don't have access to Pegasus, I'm not able to run a test on my end to verify whether it resolves the issue.

Instructions

• Update multilang-support Dockerfile CUDA argument to CUDA 12.8
• Update espnet-tts and espnet-tts-fr configurations in docker-compose.yml to be CPU-only and working with CUDA 12.8
• Update any necessary environment variables and schemas.
• Test in dev environment
• Tag
• Deploy to dev and production environments

Acceptance criteria

• multilang runs on GPU in dev and production environments
• espnet-tts runs on CPU in dev and production environments
• espnet-tts-fr runs on CPU in dev and production environments
