Change the error message from "export declaration can only be used within a module purview" to "export declaration can only be used within a module interface" to be technically accurate. The previous message was misleading because export declarations are actually within a module purview when used in module implementation units, but they are only allowed in module interface units. This addresses the issue pointed out in GitHub issue #149008 where Bigcheese noted that the diagnostic wording was incorrect. Fixes #149008
