SYSML2_ — Specification of Helper::getScalarValueType() uses unknown OCL function

The specification of Helper::getScalarValueType() uses the unknown OCL String function includes:

t.qualifiedName.includes('PrimitiveTypes::UnlimitedNatural')

To check if a string is part of another string, the function indexOf() should be used instead.

The issue was accidentally introduced by SYSML2_-300 in ballot #3.

Replace includes() by indexOf()

includes() is not a supported OCL string function and should be replaced by indexOf(), which checks if a given string is a part of another string.

The operation should also check if t.name and t.qualifiedName have defined values.
