Description of problem:
The documentation mentions we can specify a GID but it does not work.
"""
The GID is optional and must already exist in the image, be created by a package, or be created by the blueprint [[customizations.group]] entry. 
"""

Version-Release number of selected component (if applicable):
osbuild-composer-46.3-1.el8_6.x86_64
osbuild-53-2.el8.noarch

How reproducible:
Always

Steps to Reproduce:
1. Push the below blueprint

name = "unexisting-group"
description = "reproducer unexisting group"
version = "0.0.1"
modules = []
groups = []
distro = ""

[[customizations.group]]
name = "foo"
gid = 9045

[[customizations.user]]
name = "foo"
description = "foo user"
password = "$6$R4EexOTlkvDDwsK8$WkL4pU.JGHSO9LmpI/SMKYbunZU.t7BYLsZs1B9m0SeOH4RBICGlbScNRl0jUri3CBwasAd/sdZMkDp4SGoBq."
home = "/home/foo"
shell = "/usr/bin/bash"
groups = ["foo", "wheel"]
uid = 9045
gid = 9045

2. Compose an image
