Create a new field in `PyImport` to obtain the line of code that contains the import.

Is your feature request related to a problem? Please describe.
I'd like to see the body of the import statement in addition the the constituents.

Describe the solution you'd like
We have:

class PyImport(BaseModel):
    from_statement: str
    imports: List[str]

But it'd be nice to have:

class PyImport(BaseModel):
    from_statement: str
    imports: List[str]
    code_body: str

Describe alternatives you've considered
Obtain it manually by slicing the file with the lines of code.

Additional context
None.
