[Release] langchain-ai/langchain langchain-fireworks==1.3.1: langchain-fireworks==1.3.1

langchain-fireworks version 1.3.1 is a patch release that addresses three key issues: requiring explicit API key configuration in FireworksEmbeddings, fixing a release versioning issue, and correcting how ToolMessage text content blocks are processed by removing non-wire protocol keys. This update ensures proper authentication handling and improves compatibility with the Fireworks API.

• •API key is now required in FireworksEmbeddings configuration to prevent authentication failures
• •ToolMessage text content blocks are sanitized to remove non-wire protocol keys for proper API compatibility
• •Patch release (1.3.1) addresses critical bugs from 1.3.0 version
