t6200: use test_commit_bulk

There's a loop that creates 30 commits using test_commit. Using test_commit_bulk speeds this up from: Benchmark #1: ./t6200-fmt-merge-msg.sh --root=/var/ram/git-tests Time (mean ± σ): 1.926 s ± 0.240 s [User: 1.055 s, System: 0.963 s] Range (min … max): 1.431 s … 2.166 s 10 runs to: Benchmark #1: ./t6200-fmt-merge-msg.sh --root=/var/ram/git-tests Time (mean ± σ): 1.343 s ± 0.179 s [User: 766.5 ms, System: 662.9 ms] Range (min … max): 1.032 s … 1.664 s 10 runs for an average savings of over 30%.
