docs: invite people to define GPT partition types for all archs now

The discovery partitions spec so far suggested we should define
arch-specific partition type uuids only for archs that have EFI. Let's
change that and invite people to define them for any arch. Why? Even if
GPT is defined as part of the UEFI spec it's quite useful independently
of it, too. Specifically, our image dissection logic makes use of it,
i.e. systemd-nspawn, systemd-gpt-auto-generator, systemd-repart,
RootImage=, portable services, and so on. None of these tools are
related to UEFI in any way.

Hence, let's open this up.

 ### Why did you only define the root partition for these listed architectures?
 
-The automatic discovery of the root partition is defined to operate on the disk
-containing the current EFI System Partition (ESP). Since EFI only exists on
-x86, x86-64, ia64, ARM, LoongArch and RISC-V so far, we only defined root
-partition UUIDs for these architectures.  Should EFI become more common on
-other architectures, we can define additional UUIDs for them.
+Please submit a patch that adds appropriate partition type UUIDs for the
+architecture of your choice should they be missing so far. The only reason they
+aren't defined yet is that nobody submitted them yet.
 
 ### Why define distinct root partition UUIDs for the various architectures?
