Description

Amended the test to ensure that two numbers are passed as arguments, for the challenge to pass.

Tested locally - with the new test, the following conditions do not pass:

1. Function call with no arguments - functionWithArgs();
2. Function call with a space as argument(worked earlier, as reported by OP) - functionWithArgs( );
3. Function call with only one number as argument - functionWithArgs(8 );

Also updated the challenge instruction to specify that two numbers must be passed as function arguments.

Closes #13280
