[feature req] Vlan data improvements

[hp197]

Hi,

The site_id field in vlans is noted deprecated by new versions of netbox:

This gives me a problem, as I like to receive all vlans of a site for provisioning of devices.
But since there is no netbox_vlan_groupS datasource, I cannot traverse anymore from site_id to a list of vlans once this change occurs.

Solution to this would be to add a netbox_vlan_groups datasource, much like the netbox_vlans, who returns a list of matching groups.
Secondly (while at the vlan code), netbox_vlan_group (single) datasource would really benefit from a id filter input, because the netbox_vlans returns the group_id (and not the name). So currently there is no way to work back the relations.

output of netbox_vlans:

[{
  description = "IPMI/DRAC/ILO Management Interfaces"
  group_id    = 6
  name        = "ipmi"
  role        = 6
  site        = 1
  status      = "active"
  tag_ids     = [
    11,
  ]
  tenant      = 1
  vid         = 1104
}]

never waste a feature request with some good old contribution 🎉

Note that im not a go developer, my contribution is as good as claude haiku 4.5 is ;-)
