Update docs about fdisk/gdisk support for discoverable partitions

This updates the docs about using fdisk/gdisk to make partitions with the right
partition type UUID as defined in the discoverable partitions spec.

Improve wording/grammar/formatting, and reflect that gdisk supports this as
well nowadays; see https://www.rodsbooks.com/gdisk/revisions.html

 ### What partitioning tools will create a DPS-compliant partition table?
 
-As of util-linux 2.25.2, the fdisk tool provides type codes to create the root,
-home, and swap partitions that the DPS expects, but the gdisk tool (version
-0.8.10) and its variants do not support creation of a root file system with a
-matching type code.  By default, fdisk will create an old-style MBR, not a GPT,
-so typing 'l' to list partition types will not show the choices that the root
-partition with the correct UUID.  You must first create an empty GPT and then
-type 'l' in order for the DPS-compliant type codes to be available.
