ci: update kaniko cache config

Update kaniko cache configuration to improve build times.

- Add `--cache-ttl` to control cache lifespan
- Add `--cache-dir` to specify cache directory
- Add `--snapshot-mode=redo` to ensure cache consistency
- Add `--use-new-run` to leverage latest kaniko features
- Remove `--log-format` and `--log-timestamp` as they are
  not needed
- Add `--compressed-caching` to optimize cache size
