doc: allow multiple initrd entries per BLS snippet
sd-boot already supports that anyway, and the Fedora folks asked for
this on the fedora mailing list, hence let's simply add this.

This is usually the kernel version and is intended for use by OSes to install multiple kernel versions at the same time with the same `title` field. This field shall be in a syntax that is useful for Debian-style version sorts, so that the boot loader UI can determine the newest version easily and show it first or preselect it automatically. This field is optional. Example: `3.7.2-201.fc18.x86_64` * `machine-id` shall contain the machine ID of the OS `/etc/machine-id`. This is useful for boot loaders and applications to filter out boot entries, for example to show only a single newest kernel per OS, or to group items by OS, or to maybe filter out the currently booted OS in UIs that want to show only other installed operating systems. This ID shall be formatted as 32 lower case hexadecimal characters (i.e. without any UUID formatting). This key is optional.

It is recommended that every distribution creates a machine id and version specific subdirectory below `$BOOT` and places its kernels and initial RAM disk images there.
