vmware_guest: cast vlan to int or str when relevant (#39726)

`network['vlan']` should be a VLAN ID
Integers passed around using jinja variable references are
converted to strings (see # 9362)
The # 32738 PR should allow using 'NativeType' in ansible
Explicitly converting to integer will make the module works
as expected with or without the NativeType support

`network['vlan']` can also be a VLAN NAME (fallback)
Explicitly converting to string will make the module works
as expected with or without the NativeType support
