Revert "tdf#59674 Word export: set a tabstop at numbering IndentAt"

This reverts commit 5ad17c85dc93973c0cbb1d633b9eed144f0677de
for the benefit of all mankind, and specifically tdf#136644.

Reason for revert: LO's UI for this is totally messed up,
so I want to completely get out of anything to do with
numbering/bullets.

It is inconsistent with how it handles default tab stops
(delete all when none are shown and things act different),
it doesn't always increment levels properly,
and does all kinds of weird things.
