Add missing API documentation for DataPathAddr

[thaJeztah]

Commit 0307fe1 added
a new DataPathAddr property to the swarm/init and swarm/join
endpoints. This property was not yet added to the
documentation.

Relates to #32717

sigh; looks like there were issues with Docker Hub search

we need to rewrite that test to a unit test, no need to test if Docker Hub is working
