Subject: [PATCH] docs(pregel): One-line markdown formatting quick-fix (#4023)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Description

I noticed a very minor issue in the formatting of the Concepts > Pregel
doc:
(https://langchain-ai.github.io/langgraph/concepts/pregel/#high-level-api)
(https://github.com/langchain-ai/langgraph/blob/main/docs/docs/concepts/pregel.md)

You can see in the image below that there is a python codeblock, then a
pycon block, and inside that block there is an extra
triple-backtick/code fence, and then text at the bottom, which it
appears like it is supposed to be a separate python block, like the one
above it. I.e., clearly:

```
```python
print(graph.channels)
```

is intended to be:

```python
print(graph.channels)
```

I'm pretty sure this is due to an extra whitespace character before the preceding closing code fence, which is throwing off the formatting.

My VS-Code/extensions can't really render the Markdown the way it appears on the Website, I think because of the tabs (Graph API vs. Functional API), but I noticed that if I remove the extra whitespace, the highlighting on the python codeblock is corrected:

## Fix
* Remove one whitespace character that was throwing off markdown rendering
