sphinx.ext.doctest config variable doctest_test_doctest_blocks is not respected #13858
Description
Describe the bug
The documentation for doctest_test_doctest_blocks claims that If this is a nonempty string, standard reStructuredText doctest blocks will be tested too. They will be assigned to the group name given..
It does not. Regardless of the configuration value, the doctest blocks are assigned to the default group.
How to Reproduce

bug-demo documentation
======================
.. testsetup:: Custom
from module import *
.. autoclass:: module.MyClass
conf.py
import sys
sys.path.append(".")
extensions = [
"sphinx.ext.autodoc",
"sphinx.ext.doctest",
]
doctest_test_doctest_blocks = "Custom"
module.py
class MyClass:
"""
MyClass docstring
Examples
--------
>>> instance = MyClass("value")
"""
def __init__(self, value: str):
self._value = value
When running sphinx-build -M doctest, observe failure:
**********************************************************************
1 item had failures:
1 of 1 in default
1 test in 1 item.
0 passed and 1 failed.
***Test Failed*** 1 failure.
Doctest summary
===============
1 test
1 failure in tests
0 failures in setup code
0 failures in cleanup code
build finished with problems.
Changing the ..testsetup directive group to default makes the build succeed, even though doctest_test_doctest_blocks specifies that doctest blocks should be added to a Custom group

It seems to me that the configuration variable simply isn't wired through:
