Update the return function regex

[ahmadmsaleem]

Description

There was a need for cleaner return functions instead of the old one, because the :: is so confusing for people who learn by looking at codes

function getScore(player: player) :: number: old
function getScore(player: player) returns number: new

I personally like this addition, idk why we never did it?! hopfully it doesn't break anything we didn't think of.

Can you update examples to add 1 more example using this new addition.

The code for StructFunction.java and EffReturn.java have been updated with two new examples

After testing this for an hour, everything seems fine. Is there anything else I should test?

function itemTest1() returns         item:
    return itemTest2()

function itemTest2() returns item:
    return itemTest2()

function itemTest3() :: item:
    return diamond sword
