Bump due to security issues

[mthbernardes]

Bump the following libs due to a security issue

• io.netty/netty-codec (CVE-2021-43797)

Checklist

• [x] tests
• [ ] updated CHANGELOG (the "unreleased" section)

[cddr]

There's a whole bunch of netty related libraries that should possibly be kept in sync (see above/below the line you changed).

Any news on this? Looks like the netty libs have moved on further to worth bumping up again and getting a release cut
