Fix wrong _errorLine in operation/shader_module/compilation_info.spec.ts (#2088)

This patch fixes the wrong value of _errorLine of the shader named
'carriage-return' in kInvalidShaderSources. The correct error line
should be 5:
line 1: \n
line 2: @vertex fn main() -> @Builtin(position) vec4<f32> {\r\n
line 3: \n
line 4: // Expected Error: unknown function 'unknown'
line 5: return unknown(0.0, 0.0, 0.0, 1.0);
