LangChain doc builds are currently
[broken](https://vercel.com/langchain/langchain/ExxE3a6SSZVa7RSRUDB3mzHDpsvV?filter=errors).

- LangChain docs page hosts LangServe readme:
https://python.langchain.com/docs/langserve/;
- The readme is [downloaded from
github](https://github.com/langchain-ai/langchain/blob/22a8652eccd9023cd41ea0f6924575ce87c28756/docs/Makefile#L49)
when docs are built;
- A
[script](https://github.com/langchain-ai/langchain/blob/master/docs/scripts/resolve_local_links.py)
resolves local links in the readme to point to the LangServe github.

This script assumes local links are prefixed with `./`

Issue: 404 when you click the [LangChain
Templates](https://github.com/langchain-ai/langchain/blob/master/templates/README.md)
in readme. As templates dir has been removed on latest langchain master.

Fix: Just remove it to avoid 404 as example dirs is enough, look like
(my local vs code)
