I left off setting `interpreter_constraint`, which resulted in using an invalid Python version to build the Pants distribution. https://github.com/pantsbuild/pants/runs/2740478603#step:9:1179

This slipped through because `[ci skip-build-wheels]` was in the PR pantsbuild#12017 due to the pre-commit hook. This PR fixes the pre-commit hook to avoid that specific situation from happening.
