fix: move pgbackrest logrotate config to follow repo convention

- Move from pgbackrest_config/ to logrotate_config/ to match the
  existing pattern for all other logrotate configs in the repo
- Deploy via the finalize-ami.yml loop rather than setup-pgbackrest.yml
- Add size 50M cap to prevent logs growing unbounded between daily
  rotations during large backup/restore operations
