chore(provider/gateway): update gateway model settings files (#20282)

Automated update of the gateway model settings files.

Regenerated from the upstream gateway model list by
[`update-model-settings.yml`](https://github.com/vercel/ai/blob/main/.github/workflows/update-model-settings.yml)
([this run](https://github.com/vercel/ai/actions/runs/33777859909)).
Merging this PR is what surfaces newly-released gateway models as IDE
autocomplete suggestions when users type a model string with
`@ai-sdk/gateway`.

See the workflow file for details on cadence and scope.
