Description of problem:
While other GRUB themes work, `breeze` does not.


Version-Release number of selected component (if applicable):
grub2-breeze-theme-5.24.5-1.fc36.src.rpm


How reproducible:
I installed `grub2-breeze-theme` with `sudo dnf install grub2-breeze-theme` and changed `/etc/default/grub` to:
```
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
#GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 initcall_blacklist=simpledrm_platform_driver_init"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
GRUB_FONT=/usr/share/grub/unicode.pf2
GRUB_THEME="/boot/grub2/themes/breeze/theme.txt"
```
I re-generate grub with this command: `grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg`


Actual results:
The theme is not applied, it looks like `GRUB_TERMINAL_OUTPUT="gfxterm"`.


Expected results:
The theme is applied.


Additional info:
As a sanity check, I installed another theme ([ant](https://github.com/bug3/ant)), and it worked.
