Docs: Warning for Mako in docs build

[JacobCoffee]

Summary

Docs building has a new warning on main:

/Users/jcoffee5/git/public/litestar-org/litestar/litestar/contrib/mako.py:docstring of litestar.contrib.mako.MakoTemplate.__init__:1: WARNING: py:class reference target not found: R

is caused by litestar.contrib.mako.MakoTemplate.__init__'s super inheriting and using R = TypeVar("R") somehow.

litestar/litestar/template/base.py

Lines 110 to 114 in d536235
