docs: avoid needing to render API docs for any preview/render invocation (#10106)

Because we include a generated file, this forces developers to render
API docs, or delete the file that references the generated file. This PR
fixes that by deleting the file using the include, and referencing the
included file directly in `_quarto.yml`
