Code suggestion

[notJoon]

Description

Added a feature that suggests code modifications when it's possible to analyze the AST.

This feature demonstrates how the code could be improved. Additionally, I've included separate notes to explain how the code has changed and the resoning behind these decisions.

Example

error: unnecessary-else
 --> main.gno
   |
 6 |         if x {
 7 |                return 1
 8 |         } else {
 9 |                return 2
10 |         }
   | ~~~~~~~~~~
   | unnecessary else block

Suggestion:
 6 | if x {
 7 |    return 1
 8 | }
 9 | return 2

Note: Unnecessary 'else' block removed.
The code inside the 'else' block has been moved outside, as it will only be executed when the 'if' condition is false.
