MongoDB usage is broken in ros2

[rhaschke]

The package mongodb (version 3.6) is not released anymore since Ubuntu Jammy.
Official install instructions, suggest installing from a proprietary package repository:
https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-ubuntu

Unfortunately, installable versions 6.0 and 7.0 of mongodb are not compatible with the still released C++ driver package libmongoclient-dev. Older versions do not install for some reason (and it is unclear whether they are compatible).

It is unclear where to find a debian package of the new C++ driver. The old, legacy driver, doesn't build anymore.
Debian experimental seems to provide a new driver: https://tracker.debian.org/pkg/mongo-cxx-driver.

Summarizing, MongoDB support is broken in recent ros2 distros.
