[llvm] workflows/release-binaries: Fix problem with python installation on macos-14 (PR #101774)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/101774

python3 wasn't able to see modules installed by pip, so we need to use the setup-python action to ensure that the default pip and python3 both use the same prefix.

See https://github.com/actions/runner-images/issues/10385
