* Use zeropool.Pool to workaround SA6002 I built a tiny library called https://github.com/colega/zeropool to workaround the SA6002 staticheck issue. While searching for the references of that SA6002 staticheck issues on Github first results was Prometheus itself, with quite a lot of ignores of it. This changes the usages of `sync.Pool` to `zeropool.Pool[T]` where a pointer is not available. Also added a benchmark for HeadAppender Append/Commit when series already exist, which is one of the most usual cases IMO, as I didn't find any.
