Release 2022.02.17

Upgrade instructions

From #3768 (Remove TimeDependence/Composition.?pp):

There is no more Composition TimeDependence. If a composition of simple maps is desired, then it should be written explicitly.

From #3799 (Functions in ApparentHorizons/Tags.cpp are now free functions.):

The only interface difference (other than the existence of new functions) is that ah::Tags::LaplacianRadius is now a Scalar<DataVector> instead of a DataVector.
