[cloud] Update disk log console tool descriptions

Update the descriptive text for the disk log console tools to remove
references to INT13, since these now work for both BIOS and UEFI disk
log consoles.

Leave the script names as {aws,gce,ali}-int13con, to avoid breaking
any existing tooling that might use these names.
