fix: Match width of ascii and unicode secondary file start The current [unicode secondary file start](64ca23b623/compiler/rustc_errors/src/emitter.rs (L2991)) is only three characters, whereas the ASCII variant and normal [file start](64ca23b623/compiler/rustc_errors/src/emitter.rs (L2983-L2984)) are four characters. This slight difference caused the paths following a Unicode secondary file start to not align with other structured elements.
