DOCS - Clarify the publication 'publish_via_partition_root' default value.

Hi,

When reading the docs for the publication parameter
'publish_via_partition_root' [1], I felt there was too much mental
gymnastics required to understand the meaning of "the latter is the
default."

Why not just say clearly what the default value is?

PSA: a patch to do that.
