QA:Testcase partitioning custom no swap

Description

An installation without specifying a swap partition. When a system has sufficient memory, the installer should warn, but not restrict this request.

Setup

1. Prepare a test system with a working, supported storage device of sufficient size for a Fedora install, and a Fedora installation medium that uses the GTK-based installer. Do not use Fedora Workstation live on Fedora 41+, as that uses the webui-based installer.

How to test

1. Boot the GTK-based installer using any available means. Do not use Fedora Workstation live on Fedora 41+, as that uses the webui-based installer.
2. Proceed to the installer's main screen, making sensible choices, and enter the Installation Destination screen.

Expected Results

# Anaconda warns that system performance may suffer without a swap partition
# Anaconda allows the installation to complete successfully for systems with sufficient system memory (consult the Hardware Overview section of the release notes for minimum hardware requirements).  For systems with insufficient memory, anaconda must require the presence of a swap partition.
# Reboot successfully into installed system
# Confirm that no swap partition is in use (/proc/swaps)
