Description

Problem*

Resolves https://github.com/noir-lang/noir/issues/6060

Summary*

We had ExpressionKind::Interned as always requiring a semicolon to separate two expressions, but this isn't true for all expression types (blocks, if). We can't check what is interned so I just always made the semicolon optional.
