Description:

Currently, benchmark report is just a static markdown file lies in https://github.com/envoyproxy/gateway/blob/main/test/benchmark/benchmark_report.md.

It's very inconvenient to update this report, need to raise a PR everytime, so I propose to include this report into release as an assets.

Everything that is relevant to benchmark report (including report markdown, cpu & memory profiles files, images etc.) can be packed into benchmark_report.zip and got published it with release as an assets.
