Bug Description

For classes such as GenericConstantMaterial that use templating to create non-AD and AD versions, the corresponding documentation pages do not contain a list of input files that use the class even though '!syntax inputs ...' appears in the .md file.

Steps to Reproduce

See https://mooseframework.inl.gov/source/materials/GenericConstantMaterial.html as an example.

Please describe the problem you are trying to solve.
The current implementation of the barycentric coordinates are overly complicated and explicitly require the normals of triangles or edges. There are simpler ways to implement this.

Describe the solution you propose.

• Simplify math/barycenter.[ch]pp
• Remove Edge::computeNormal() as it is unnecessary.

**Describe alternativ

we should add .ipynb to the gitignore - notebooks are out-of-scope for this repo. In the past we have had some notebooks be committed which adds a large volume of code to the log that is later removed

Although this is a more complicated scenario and it would be complicated to provide specifications, it would be good to have geometry files somewhere.

For historical reasons, we don't have access to the source geometry files anymore. Reconstructing the geometry or adapting the tutorial to a known geometry would be useful, so that if anyone wants to change one of the solvers, they can do it.
