docs: Remove docs for non-existing pxe_unload command

Remove the documentation of the pxe_unload command from the
docs/grub.texi file.

The pxe_unload command is not implemented in the grub source
at this time at all. It appears to have been removed in commit
671a78acb (cleanup pxe and efi network release).
