fix: prevent auto-merge when tests fail

Two issues fixed:
1. README.md: fix alphabetical order of go-date-fns/go-datebin in Date
   and Time section (caused TestAlpha to fail)
2. pr-quality-check.yaml: add tests job as dependency for auto-merge,
   so PRs cannot be auto-merged when tests fail

Previously the auto-merge job only depended on quality checks, ignoring
the tests workflow result entirely. Now auto-merge requires both quality
AND tests to pass.
