Fix the order of the arguments being inputted into result.append in print() from the Type Function Runtime

[karl-police]

This fixes print from the Type Function Runtime, when you use , inside of print() within a type function.

Currently, in the Type Function Runtime, if you do print(1, 2)

It's going to append \x1 based on the size_t of \t, because it's in the wrong function argument order.

It's not going to use \t instead it creates \x1 because of a copy paste mistake from the original print

result.append has a different function order

Currently, it's the wrong order

This is the right way

Your PR is missing flag for the change and a unit test.

[vegorov-rbx]

Flags are easy to add.

You declare a flag at the start of the file with 'Luau' at the start of the name:
LUAU_FASTFLAGVARIABLE(LuauTypeFunPrintFix)
You then have new code under if (FFlag::LuauTypeFunPrintFix).

In the unit test file, you fetch the existing flag using LUAU_FASTFLAG(LuauTypeFunPrintFix) and inside the test case place: ScopedFastFlag luauTypeFunPrintFix{FFlag::LuauTypeFunPrintFix, true};

Alright, gimme a second.

or more time, my Github Desktop is exploded and I forgot that I had to add * temporarily to .gitignore
