Update version and improve release note generation

Update version from 4.4.11 to 4.4.12

- Bump version in version.go
- Enhance release note generation in Makefile to use JSON output from orla and fallback to raw output if JSON parsing fails
- Improve test script to verify minimum super k-mer length is >= k (default k=31)
