Update TiDB test matrix to latest versions and add TiUP updates

- Update TiDB versions to latest of each minor series:
  - 6.1.0 → 6.1.7 (latest 6.1.x)
  - 6.5.3 → 6.5.12 (latest 6.5.x)
  - 7.1.5 → 7.1.6 (latest 7.1.x)
  - 7.5.7 → stays (already latest 7.5.x)
  - 8.1.0 → 8.1.2 (latest 8.1.x)
  - 8.5.3 → stays (already latest 8.5.x)

- Add TiUP update steps to ensure latest playground component:
  - Update TiUP and playground in GitHub Actions workflow
  - Update TiUP and playground in tidb-playground.sh script

This ensures we test against the latest patch releases with bug fixes
and improvements, and use the latest TiUP playground features.
