text: Title: Modify regex
  Body: ollama:deepseek-coder-v2
  Generates code like bellow
  
  ```
   ```python
  def add(a, b):
      if b == 0:
          return float('inf')  # Using infinity to avoid division by zero
      else:
          return a / b
  add(1,0)
  ```
  where there is space before ```python causing the output to be incorrect. Need to modify the lang_indicator as follows.
  
  lang_indicator = r"^\s*```[a-zA-Z0-9]*\s*\n"
