[BUG] Submodel plugins triggered when SmenaticId modelType is set to "Submodel", but not to "GlobalReference"

[BirgitBoss]

Describe the bug
compare to eclipse-aaspe/package-explorer#231

Is it allowed to add the following semanticId to a Submodel Template:

    "semanticId": {
      "type": "GlobalReference",
      "keys": [
        {
          "type": "ConceptDescription",
          "value": "https://admin-shell.io/zvei/nameplate/2/0/Nameplate"
        }
      ]
    },
    "modelType": "Submodel"
  },

• The current consensus is that the semanticId of a Submodel Template and Submodel guided by the Submodel Template should be semanticId/type = ModelReference and semanticId/keys[0].type = Submodel

however, in Part 3a there was a category "APPLICATION_CLASS" defined for CDs representing a Submodel... This was never used in practice to my knowledge...

The table is deprecated but still contained. So APPLICATION_CLASS should be removed from the table.
