Please refer to: https://issues.redhat.com/browse/RHELPLAN-150026

When specifying user and group customizations under the [[customizations.files]] section, warnings appear even though the configuration is valid. These warnings should not be present and may mislead users into thinking their configuration is incorrect.

User and group customizations under [[customizations.user]] will be deprecated.

However, this deprecation does not apply to user and group options under [[customizations.files]], which will remain supported.

Steps to Reproduce:

1. Sample blueprint:

1. composer-cli blueprints show test

   name = "test"
   description = "a test blueprint"
   version = "0.0.2"
   modules = []
   groups = []
   distro = ""
   [[packages]]
   name = "bash"
   version = "*"
   [customizations]
   [[customizations.files]]
   path = "/etc/systemd/system/duagon-sync-rtc.service"
   user = "root"
   group = "root"
   mode = "0644"
   data = "[Unit]\nDescription=Sync the system clock to /dev/rtc1 device\nWants=duagon-sync-rtc.timer\n\n[Service]\nType=oneshot\nExecStart=/bin/bash -c 'hwclock -v --systohc --rtc /dev/rtc1'\n\n[Install]\nWantedBy=multi-user.target default.target\n"
   

    

2. Warning:

1. compose start test edge-container

   Warning: Please note that user customizations on "edge-container" image type are deprecated and will be removed in the near future
   Compose f1f12380-8687-490b-83cc-0efe565082d1 added to the queue
   

    

Expected Behavior:

No warnings should be generated if the user and group attributes are correctly set under [[customizations.files]].

Actual Behavior:
Warnings appear unnecessarily, potentially causing confusion.

Environment:

RHEL 9.5
