Add 2D or 3D lid-driven cavity with flexible bottom tutorial case

[IshaanDesai]

The 2D lid-driven cavity is a classic CFD case, and it has been further worked into a relatively easy-to-do FSI case by having a flexible structural bottom surface. A lid-driven cavity with a flexible bottom is shown to work in the thesis of Benjamin Uekermann in Section 3.7.3 and has also been discussed in a Discourse post for other solver combinations: https://precice.discourse.group/t/lid-driven-cavity-with-flexible-bottom/364. Adding such a case as a tutorial should be straightforward.

In addition to the existing solver combinations, the case has also been simulated as part of reviving the Fluent-adapter in https://github.com/precice/fluent-adapter/pull/26 where Fluent is used as the fluid participant and a simple CSM solver written in Python is the solid participant. The fluid Fluent part of this case can be used in the creation of this tutorial.
