add info around dimension and coordinate value

also on the allowed types section on the main constraint page and not just the syntax page
(it was mentioned in the example but not by the type list)

unrelated to the index bits, but something I noticed on the constraint PR but that didn't get updated before it was merged

 [NOTE]
 Because storing lists of xref:values-and-types/vector.adoc[`VECTOR`] values is not supported, property type constraints cannot be created for `LIST<VECTOR<TYPE>(DIMENSION) NOT NULL>`.
+Additionally, `VECTOR` property type constraints must be created with a specific dimension and coordinate value, where the dimension must be greater than `0` and less or equal to `4096`.
+For more information, see xref:values-and-types/vector.adoc[Values and types -> Vectors].
