SYSML21 — redefinition of directed action features

The last sentence of the 3rd paragraph of this section states:

"The redefining parameters must have the same direction as the redefined parameters."

However, this isn't the most clear as an "inout" could be redefined to an "in", an "out" or an "inout". So the direction isn't the same. KerML allows us to redefine the direction (see: https://groups.google.com/g/SysML-v2-Release/c/ooETIZaZLhI). We should update this wording to be more clear/accurate. I propose:

"The redefining parameters must have the same or more specific direction as the redefined parameters."
