Incorrect grub menu appears in live session

[Yousuf 'Jay' Philips]

When loading the live ISO session, an accessibility icon should appear, which then takes you to a menu where you can select language and other options, but this hasn't been present for many months in Hirsute daily ISOs for xubuntu. Instead a simple grub menu appears.

Status changed to 'Confirmed' because the bug affects multiple users.

Alan Pope confirmed that Lubuntu shows the grub menu.

Accessibility icon & language selection from preboot environment was only ever possible on x86, when booting in bios mode, when booting with isolinux.

focal was the last release to use isolinux.

All releases since focal use unified grub2 bootloader on x64 for both bios & efi boot, thus the experience is the same on both.

The expectation is for the boot to complete into `maybe-ubiquity` mode which should present language selection as the first screen when one elects to try or install.
