Drop automodule from deprecated nlinalg/slinalg doc pages

The deprecation pages still carried `.. automodule:: pytensor.tensor.{nlinalg,slinalg} :members:` directives. Each automodule
walks the module's `__dir__`, which on the new shims returns every
moved name and triggers `__getattr__` per name — emitting a
DeprecationWarning per attribute on every doc build, and producing
duplicate doc entries that already exist on the new
:ref:`libdoc_linalg` page.

Drop the automodule blocks; the pages are now pure deprecation notices
that point at `pytensor.tensor.linalg`.
