Dead link in cg_recipes

[NilsIrl]

On this page in the first paragraph the link to transformation types gives a 404 error as it links to https://nalgebra.org/docs/user_guide/cg_recipes/points_and_transformations/#transformations instead of https://nalgebra.org/docs/user_guide/points_and_transformations/#transformations

The weird thing is that when running the website locally, the link is valid and that when the page first loads the link is also valid (and some javascripts modifies it such that it becomes invalid).
