feat[ux]: move exception hint to the last position

[cyberthirst]

What I did

• moved the (hint: ...) to be reported as the last item to improve the readability
• the hint should be displayed after the actual problem has been described, ie, as the last item

example:

original:

vyper.exceptions.InvalidOperation: Cannot perform decimal division on uint256

  (hint: did you mean `10 // 4`?)

  contract "tests/custom/test.vy:3", function "f", line 3:17 
       2 def f(x: Bytes[32*5]):
  ---> 3     k: uint256 = 10 / 4
  ------------------------^

new order:

vyper.exceptions.InvalidOperation: Cannot perform decimal division on uint256

  contract "tests/custom/test.vy:3", function "f", line 3:17 
       2 def f(x: Bytes[32*5]):
  ---> 3     k: uint256 = 10 / 4
  ------------------------^

  (hint: did you mean `10 // 4`?)

edit: fix the example

Description for the changelog

Given how close the 0.4.0 release is, I think it might be wise to merge after the release.
