Subject: [PATCH] docs(langgraph): Fix typo in docstring of PregelLoop.tick
 (#6407)

This is a very small PR to correct a typo in the docstring of the
`PregelLoop.tick()` method.
```python
  def tick(self) -> bool:
      """Execute a single iteration of the Pregel loop.

      Args:
          input_keys: The key(s) to read input from.

      Returns:
          True if more iterations are needed.
      """
```

Corrected to :
```python
  def tick(self) -> bool:
      """Execute a single iteration of the Pregel loop.

      Returns:
          True if more iterations are needed.
      """
```

The docstring was written in #2946 when the signature of tick was
```python
    def tick(
        self,
        *,
        input_keys: Union[str, Sequence[str]],
    ) -> bool:
```
but  it was simplified to
```python
def tick(self) -> bool:
```
in #5080
