Correct `householder_product` docs. (#68335)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68335
When discussing https://github.com/pytorch/pytorch/pull/63880, we
realised that the docs of `householder_product` were not correct. This
PR fixes this.
The new docs are slightly more difficult, but hopefully correct. Note
that this is a LAPACK function in disguise, so it is expected the
specification to be more difficult than normal.
