feat: re-make bad-quality themes

[AdisonCavani]

Themes I'm planning to remake in the next release - v3.3

Distro:

• Solus (too small contrast between logo and background)
• Ventoy (too small contrast between logo and background)

OEM:

• Aorus (bad preview image - missing menu)
• Asus (bad gradient)
• Gigabyte (bad preview image - missing menu)
• Kingston (bad preview image - missing menu)

Grub with secure boot on does not allow using custom fonts. A theme with the default grub font would be nice.
