[SPARK-50394][PYTHON][INFRA] Reduce parallelism in Pure Python librar…

…y builds ### What changes were proposed in this pull request? This PR proposes to decrease parallelism in Pure Python library builds ### Why are the changes needed? In order to make the tests more robust: https://github.com/apache/spark/actions/workflows/build_python_connect.yml https://github.com/apache/spark/actions/workflows/build_python_connect35.yml Now they fail because of OOM. ### Does this PR introduce _any_ user-facing change? No, test-only ### How was this patch tested? Will monitor the build: https://github.com/apache/spark/actions/workflows/build_python_connect.yml https://github.com/apache/spark/actions/workflows/build_python_connect35.yml ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#48932 from HyukjinKwon/reduce-parallelism. Authored-by: Hyukjin Kwon <[email protected]> Signed-off-by: Hyukjin Kwon <[email protected]>
