doc: Update README to improve Toolbox LangChain SDK installation instructions (#287)

Add the bash command to `pip install` the package directly in the README
for a quicker start.

Also add “SDK” after “Toolbox LangChain” to clearly show that “Toolbox
LangChain” is an SDK.

> [!NOTE]
> We had released the PyPI package for Toolbox LangChain SDK as
`toolbox-langchain` and not `toolbox-langchain-sdk` but it still makes
sense to call it “Toolbox LangChain SDK” in natural language.
