Remove system zlib packages from unix native dependencies

[carlossanlop]

Follow up of https://github.com/dotnet/runtime/pull/105371

We can't yet remove the system zlib packages from the package installation branches in install-native-dependencies.sh because we don't yet consume an SDK version that includes zlib-ng.

If we remove them from this script, and we attempt to run it in a new machine, then try to build runtime with:

eng/install-native-dependencies.sh
./build.sh clr+libs

We see this error:

Once we start consuming an SDK version that includes zlib-ng, we can remove those 3 references from the script: zlib1g-dev, zlib-devel and zlib-dev.

And also remove mentions of zlib in the instructions:
