Add Redis 8.0 to CI test matrix

[chrisguidry]

Redis 8.0 is now generally available, so let's test against it alongside
our existing Redis 6.2, 7.4, Valkey 8.0, and Memory backend matrix legs.

Tested locally - all 505 tests pass with 100% coverage.

Code Review for PR #210: Add Redis 8.0 to CI test matrix

Summary

This PR successfully adds Redis 8.0 to the test matrix, ensuring Docket is tested against the latest stable Redis release. The changes are minimal, focused, and consistent across all affected files.

✅ Strengths

1. Comprehensive test coverage: The PR maintains testing across multiple Redis versions (6.2, 7.4, 8.0) and Valkey 8.0, providing excellent compatibility coverage.

2. Consistent documentation updates: All documentation files (.github/workflows/ci.yml:24-26, README.md:85, docs/getting-started.md:24, docs/index.md:69) have been updated consistently to reflect Redis 8 support.

3. Proper CI matrix configuration: The Redis 8.0 entry follows the same pattern as existing versions, using appropriate redis-py version constraints (>=5).

4. Testing validation: The author confirms all 505 tests pass with 100% coverage locally, which aligns with the project's strict coverage requirements.

📋 Observations

1. Version naming consistency: The CI uses "Redis 8.0" while documentation mentions "Redis 6, 7, and 8". This is consistent with the existing pattern where CI specifies minor versions (6.2, 7.4) but docs reference major versions only.

2. Redis-py compatibility: The configuration correctly requires redis-py >=5 for Redis 8.0, which is appropriate given Redis 8's compatibility requirements.

3. Test coverage thresholds: The 100% coverage requirement is preserved for Redis 8.0 testing, maintaining the project's high quality standards.

🔍 No Issues Found

• No bugs or security concerns identified in the changes
• No performance implications - this only affects CI testing
• No backward compatibility issues - changes are additive only
• Test coverage maintained at 100% as required

✅ Recommendation

This PR is well-crafted and ready to merge. The changes are minimal, correct, and maintain consistency across the codebase. Adding Redis 8.0 to the test matrix is important for ensuring continued compatibility with the latest Redis release.

The PR has already been approved by @parkedwards, and I concur with that assessment.
