doc(Algebra/Module/LinearMap/End, LinearAlgebra/Dual): fix typos in d…

…ocstrings (#11170)

Fix two typos:
* In `LinearAlgebra/Dual`, the doctring of `TensorProduct.dualDistribInvOfBasis` says "An inverse to `dual_tensor_dual_map` given bases.", but `dual_tensor_dual_map` is now called `TensorProduct.dualDistrib`.
* In `Algebra/Module/LinearMap/End`, the doctstring of `LinearMap.smulRight` says "When `f` is an `R`-linear map taking values in `S`, then `fun ↦ b, f b • x` is an `R`-linear map.". The map should be `fun b ↦ f b • x`.
