Update Netty to 4.1.77.Final

Resolves #514

Updates Netty to 4.1.77.Final along with reactor-bom to 2020.0.19. It seems like 2020.0.19 is newer than 2022.0.0-M2 and contains compatible Netty dependencies.

The 2022.0.0 development line of Project Reactor ships a major version increment compared to the 2020.x development line.

Oh, ok. So what is the course of action here? There's no new release for 2022.0.0 line.

[mp911de]

Did you test whether the newer netty version works against Reactor Netty 2022.0.0-M2? There should be no need to upgrade the Reactor version for now.

[jczuchnowski]

Yes, Netty 4.1.77.Final works fine with Reactor 2022.0.0-M2. But this doesn't have any effect on the target project, as it still uses 4.1.76.Final from Reactor.

I was able to force my project to use Netty 4.1.77.Final by just explicitly adding the relevant dependency to build.sbt:

"io.netty" % "netty-transport-native-epoll" % "4.1.77.Final"

And this works regardless of this PR.

So I suppose we can treat it as a workaround for the time being.

Care to update the PR to include just the netty version change and roll back the reactor change?

[jczuchnowski]

Done.

Thank you for your contribution. That's merged and backported now.
