Adjust get_function/to_pipeline input parameter order as user's input.

[mingjerli]

Description

Originally, the order is based on the appearance of the session code. It is actually not very desirable, especially in multiple sessions cases.

Basically, if we ran

lineapy.get_function(['a'], input_parameters=['x','y'])

we might get

def run_all_sessions(x, y)

or

def run_all_sessions(y, x)

depending on the ordering of variable x and y appearance in the session code.

This PR will make it always in the order of the user's input; i.e.,

def run_all_sessions(x,y)

How Has This Been Tested?

Update the test result of the existing test case.

The modified existing test case is an example of the user's input does not agree with what the appearance order in the original code, so we need to modify the case.
