'readLine' can be replaced with 'readln' or 'readlnOrNull'

Reports calls to readLine() that can be replaced with readln() or readlnOrNull().

Using corresponding functions makes your code simpler.

The quick-fix replaces readLine()!! with readln() and readLine() with readlnOrNull().

Examples:

    val x = readLine()!!
    val y = readLine()?.length

After the quick-fix is applied:

    val x = readln()
    val y = readlnOrNull()?.length
