Validate Feature Comparison docs page

[itrofimow]

There is a Feature Comparison with other Frameworks page in the docs, which i believe should be verified by the corresponding maintainers/communities to avoid unintentional inaccuracies.

Not sure about go-micro and dapr, but drogon maintainers are pretty active in github or Telegram, and rust community seems to be just active on its own, so these two could be a good starting point in my opinion.

@userver-framework/userver-maintainers do you find this suggestion appropriate?

P.S. It's probably worth noting axum alongside/instead of actix-web
