• Modify the flag from --output to --output-dir. The --output flag has been modified to --output-dir in this tiup/211 PR, but the flag in the tiup/tiup-bench.md document is not updated. Since this change is before TiDB v4.0, this PR needs to cherry pick from v4.0 to v6.2. (issue: 文档中所有--output 都是 应该都是 --output-dir #10803)
• Add the --output-type=csv in each command to generate CSV file (suggestions from JaySon-Huang)
• Remove the enable pprof step (suggestions from JaySon-Huang)

不过假如用户执行的时候，在 127.0.0.1:4000 上有 tidb 或 mysql，那么是可以运行的。文档改动先忽略这个报错的问题好了。
