fix(bedrock): don't default baseURL to anthropic API when using bedrock

Aleks Clark created 1 week ago

When useBedrock is true, the DefaultURL ("https://api.anthropic.com") was
being set on providerOptions.baseURL in New(). This caused LanguageModel()
to append option.WithBaseURL("https://api.anthropic.com") after
bedrock.WithConfig had already set the correct bedrock-runtime URL,
overwriting it.

Only set the default base URL for non-bedrock providers. Bedrock gets its
URL from bedrock.WithConfig() in the SDK.
