[generative_ai]: Translation "with LLM" samples are not working anymore.

In which file did you encounter the issue?

N/A — The samples in issue are written as Markdown. I worked on replacing them with actual Python samples.

Did you change the file? If so, how?

No.

Describe the issue

Both "Translation LLM" samples appear not working anymore (sample 1, sample 2).
The SDK fails to create the endpoint using the cloud-translate-text LLM provided in the documentation:

from google.cloud import aiplatform

endpoint = aiplatform.Endpoint('projects/PROJECT_ID/locations/LOCATION/publishers/google/models/cloud-translate-text')
...

Error:
