Display ANTLR4 errors only in the UI

[AntoineLeBG35]

Description:
Currently, ANTLR4 errors are displayed both in the console and in the UI. To improve clarity and user experience, these errors should be displayed only in the UI and not duplicated in the console.

Expected Behavior:

• ANTLR4 errors should appear exclusively in the user interface.
  

• No ANTLR4 error logs should be printed to the console.
