Does this change the behavior? Say that runtime 1 is java8.al2 and the second is python3.12. In the old version, that would return -1. In the new version, the return is 1 - 0, which is 1.

Ig that pair (java8.al2 vs python3.12) never hits this code, since java vs python are different names so it returns on the name comparison. and the java8 without suffix doesn't exist in INIT_RUNTIMES so that situation will never happens either. So for the real pairs (java8.al2 vs java8.al2023, java17 vs java17.al2023), we've flipped to newest-os-first per Renato's feedback.

return second_version_number - first_version_number

return 1 if first_runtime_name > second_runtime_name else -1
