Java SE 21 adds new ArrayList methods conflicting with ICommonsList

[phax]

See https://docs.oracle.com/en/java/javase/21/docs/api/new-list.html

The methods under question are:

• ArrayList.getFirst()
• ArrayList.getLast()
• ArrayList.removeFirst()
• ArrayList.removeLast()

These methods in ICommonsList need to be deprecated for removal and instead new methods with OrNull appended to their names, but with the same functionality needs be added.
