Subject: [PATCH] Switch to Anthropic -latest tags (#19615)

- Closes: https://github.com/zed-industries/zed/issues/19609

Switches us to using `-latest` tags with Anthropic models instead of
pinning to a specific date version.
See: [Anthropic Model
Docs](https://docs.anthropic.com/en/docs/about-claude/models)

This is a no-op for:
- Claude 3 Opus (`claude-3-opus-20240229`)
- Claude 3 Sonnet (`claude-3-sonnet-20240229`)
- Claude 3 Haiku (`claude-3-haiku-20240307`)

For Claude 3.5 Sonnet this will update us from
`claude-3-5-sonnet-20240620` to `claude-3-5-sonnet-20241022`. We will
also pickup any subsequent model updates automatically when Anthropic
updates the `latest` tag.

This matches the behavior for OpenAI where use `gpt-4o` as the
model_name and not `gpt-4o-2024-08-06`.
