deps: update @anthropic-ai/sdk to 0.27.3 from 0.25.2

[rootCircle]

This PR updates the version of @anthropic-ai/sdk from 0.25.2 to 0.27.3 to allow introduction of dangerouslyAllowBrowser flag in langchain as well!

Updates in upstream also include streaming helpers, introduced beta prompt caching and further streaming capabilities.

Purpose

anthropic-sdk-typescript has recently introduced support for browser from their SDK as well in v0.27.0 (pr here). But, this is still not in langchain yet!

Anthropic had been resistant to adding this feature because it can encourage a nasty anti-pattern: if you embed your API key in your client code, anyone with access to that site can steal your API key and use it to make requests on your behalf.

Despite that, there are legitimate use cases for this feature. It’s fine for internal tools exposed to trusted users, or you can implement a “bring your own API key” pattern where users supply their own key to use with your client-side app.

What it means is we can now make a call to Anthropic via Browser as well, through dangerouslyAllowBrowser flag present in ClientOptions! Also, we won't require to add that flag on our side as well, because we're importing the ClientOptions from anthropic-sdk only, instead of having our own implementation!

Hence, the invocation becomes like this!

const model = new ChatAnthropic({
  modelName: "claude-3-haiku-20240307",
  temperature: 0,
  clientOptions: {
    dangerouslyAllowBrowser: true,
  }
});

Also, I saw that in other lib, like in openai and groq, we're mandating it to allow browser by default, should we implement the same in anthropic as well?

In other libs like of groq & openai have dangerouslyAllowBrowser set to true by default! Should we have the same behavior in this as well?
