[3.10] gh-86404: Doc CI: Disable suspicious checks. (GH-26575) by JulienPalard · Pull Request #98221 · python/cpython
make suspicious is disabled on 3.11 and removed in main, as it has been replaced by sphinx-lint.
Keeping the CI enabled with it here may lead to false positives from make suspicious during documentation backports, leading to painfull backports.
