Update constraint release versions and mutation rate handling

- Modified CONSTRAINT_RELEASES to include "4.0" alongside "4.1" and "4.1.1".
- Introduced CONSTRAINT_MUTATION_RATE_RELEASES for better clarity in mutation rate table paths.
- Updated function docstrings to reflect the specific constraint mutation rate release versions.
- Adjusted the constraint_mutation_rate function to utilize the new CONSTRAINT_MUTATION_RATE_RELEASES list.
