Split method doesn't work with string interpolation and special symbols

## Compiler version 3.0.2-RC1


## Minimized code

```Scala
scala> val str = f"random\n"
val res0: String = random\n
scala> val str.split("\n")
val res1: Array[String] = Array(random\n)
```

## Expectation
The split method should remove the `\n` at the end of the string, but with Scala's string interpolation in Scala 3 the split method does not properly remove some special symbols
