fix(gitignore): split the merged bench/backups line so backups/ is ignored

Commit 2c8359f appended backups/ to the /Dockerfile.bench.v2 line, which had no
trailing newline. The result, /Dockerfile.bench.v2backups/, matched neither file,
so dumps written by scripts/backup.sh showed up as untracked and could be
committed by accident.
