Do not truncate whitespace for multi-line string

[anthonykim1]

Resolves: #23743

It seems that when people have a multi line string such surrounded by """ quotes, the white spacing inside the quote is very much intentional, and so if we detect that they are in such code-block, we would rather not normalize/truncate the white spaces for that specific code block.

Does this break sending the code to the python terminal with shfit+enter when there are doc strings in the function because it sends the function in 2 different lines?

In [1]: def foo(a):
   ...:     """
   ...:     foo return a
   ...:     """
   ...: 
In [2]:     return a
  Cell In[2], line 1
    return a
    ^
SyntaxError: 'return' outside function

@anthonykim1 good case for a unit test regardless of whether it breaks that case or not 👆

I think this might actually be a breaking scenario - @edeane ref: #24069
