core[patch]: Add TypeError handler into get_graph of Runnable (#19856) 
# Description

## Problem

`Runnable.get_graph` fails when `InputType` or `OutputType` property
raises `TypeError`.

-
003c98e5b4/libs/core/langchain_core/runnables/base.py (L250-L274)
-
003c98e5b4/libs/core/langchain_core/runnables/base.py (L394-L396)

This problem prevents getting a graph of `Runnable` objects whose
`InputType` or `OutputType` property raises `TypeError` but whose
`invoke` works well, such as `langchain.output_parsers.RegexParser`,
which I have already pointed out in #19792 that a `TypeError` would
occur.

## Solution

- Add `try-except` syntax to handle `TypeError` to the codes which get
`input_node` and `output_node`.
