Change backslashes in ML docstring

[IamPhytan]

This snippet is escaping backslashes, which creates escaped quotation marks in Python files

Snippet creates the following code :

\"\"\"sumary_line
    
Keyword arguments:
argument -- description
Return: return_description
\"\"\"

It should instead create this code :

"""sumary_line
    
Keyword arguments:
argument -- description
Return: return_description
"""
