Adds Claude Opus 5.5 (`claude-opus-5-5`) to the Anthropic Claude intro
notebook, following the same pattern as recent Claude launches. The model is
served on the global, us and eu endpoints.
Changes:
- Added a `Claude Opus 5.5` entry at the top of the "Available Anthropic Claude
models" list.
- Added `claude-opus-5-5` to the model selector in both "Select Claude model"
cells, and repointed the default to it.
- Added the corresponding `available_regions` entry (`global`, `us`, `eu`) in
both cells.
* feat: Claude Fable 5.1 Launch
* refactor: replace model/region if-elif chains with a dict lookup
Addresses review feedback on both Select Claude model cells. The mapping is
unchanged for all 20 models; only the lookup mechanism differs.
* chore: apply nbfmt
Runs the repo's own tensorflow-docs nbfmt over the notebook so the
'notebook format and lint' check passes.
* samples: Add a new sample for pre-built Pytorch deployments. It's
borrowed from the examples in community-content/pytorch_text_classification_using_vertex_sdk_and_gcloud.
* samples: Removed all training related stuff in the notebooks.
* samples: Fixed comments.
* samples: Updated readme.
* samples: Updated emails for Pytorch launch.
