Fix HostFunction with data example

[rockwotj]

This was broken because it passed in the data in the function pointer parameter and passed in NULL for the data parameter.

Commit 7cc7b35f5e8e5f25fbf85296e330c81b59f694f8

The key change in this patch is the modification of the function call WasmEdge_FunctionInstanceCreate in the "HostFunction with data example" section of the documentation. The author fixed the issue where the data was being passed in the function pointer parameter and NULL was being passed in the data parameter.

Original line:

WasmEdge_FunctionInstanceCreate(HostFType, (void *)(&Number), NULL, 0);

Modified line:

WasmEdge_FunctionInstanceCreate(HostFType, &PrintData, (void *)(&Number), 0);

This change correctly passes the function pointer parameter &PrintData and the data parameter (void *)(&Number) to the WasmEdge_FunctionInstanceCreate function.

There don't appear to be any potential problems with this change, as it's simply fixing an incorrect function call in the provided example by passing the correct parameters.
