System Info

Langchain version 0.0.184, python 3.9.13
Function parse_json_markdown in langchain/output_parsers/json.py fails with input text string:
```json
{
"action": "Final Answer",
"action_input": "Here's a Python script to remove backticks at the beginning and end of a string:\n\n```python\ndef remove_backticks(s):\n return s.strip('`')\n\nstring_with_backticks = '`example string`'\nresult = remove_backticks(string_with_backticks)\nprint(result)\n```\n\nThis script defines a function called `remove_backticks` that takes a string as input and returns a new string with backticks removed from the beginning and end. It then demonstrates how to use the function with an example string."
}
```

Potential case of error:
match.group(2) in the function parse_json_markdown contains only the string up to the first occurrence of the second triple backticks:

{
"action": "Final Answer",
"action_input": "Here's a Python script to remove backticks at the beginning and end of a string:\n\n

Reproduction

Called function parse_json_markdown in langchain/output_parsers/json.py with input text string:
```json
{
"action": "Final Answer",
"action_input": "Here's a Python script to remove backticks at the beginning and end of a string:\n\n```python\ndef remove_backticks(s):\n return s.strip('`')\n\nstring_with_backticks = '`example string`'\nresult = remove_backticks(string_with_backticks)\nprint(result)\n```\n\nThis script defines a function called `remove_backticks` that takes a string as input and returns a new string with backticks removed from the beginning and end. It then demonstrates how to use the function with an example string."
}
```

Expected behavior

Function parse_json_markdown should return the following json string
{
"action": "Final Answer",
"action_input": "Here's a Python script to remove backticks at the beginning and end of a string:\n\n```python\ndef remove_backticks(s):\n return s.strip('`')\n\nstring_with_backticks = '`example string`'\nresult = remove_backticks(string_with_backticks)\nprint(result)\n```\n\nThis script defines a function called `remove_backticks` that takes a string as input and returns a new string with backticks removed from the beginning and end. It then demonstrates how to use the function with an example string."
