Add correlated_pymatching decoder to sinter builtin decoder list

[inmzhang]

Some tests failed due to issues in the correlated pymatching implementation. Wait for oscarhiggott/PyMatching#166 to be merged and a new patched version released. Then bump the pymatching version requirement in decoder predicates added in this PR, e.g.:

if version.parse(pymatching.__version__) < version.parse("2.3.0"):

Update:

• Handle undetectable errors oscarhiggott/PyMatching#167 has fixed the undetectable error cases. And the fix is included in pymatching v2.3.1.
• Correlated pymatching does not support errors with probabilities greater than 0.5 yet. Therefore, I've changed the test_post_selection in _decoding_test.py a bit.
