To ease the review, you might keep the old name with an alias #define _PyObject_LookupAttr PyObject_GetOptionalAttr, and then write a second PR to update usage of the old name. (Well, just split the PR in two parts.)

You may just say:
Similar to :c:func:`PyObject_GetOptionalAttr`, but *name* is a UTF-8 encoded string.
To not copy/paste the documentation.

In all other functions with String suffix the documentation is repeated. If we are going to change this, it should be changed for all function at once.
