Add new script code Aran

[sffc]

In an upcoming release we should add the Aran script code. ICU is making the change in ICU 75:

C/C++

unicode/uscript.h

typedef enum UScriptCode {
      /** @stable ICU 75 */
      USCRIPT_ARABIC_NASTALIQ = 200, /* Aran */

Java

public final class UScript {
    /** @stable ICU 75 */
    public static final int ARABIC_NASTALIQ = 200; /* Aran */
