docs: vm/page_owner: tweak literal block in STANDARD FORMAT SPECIFIERS

A semantic conflict between commit 5603f9bdea68 ("docs: vm/page_owner: use
literal blocks for param description") and a change queued for v5.19
authored by Jiajian Ye ("tools/vm/page_owner_sort.c: support sorting
blocks by multiple keys") results in a warning from "make htmldocs"
saying:

  [...]/vm/page_owner.rst:176: WARNING: Literal block expected; none found.

This is because a literal block in ReST ends at a line which has the same
indent as the paragraph preceding it.  In this case the one with no
indent.

Indent the two "For --xxxx option:" lines by two columns and make the
whole section a literal block.

While at it, fix indents by white spaces of "ator" keys.
