Ensure z_bytes example is available on all bindings

[Mallets]

Describe the feature

It's important to show how to serialize/deserialize data through the ZBytes.
An example of Protobuf serialization should also be provided

Basic examples:

• Rust https://github.com/eclipse-zenoh/zenoh/blob/dev/1.0.0/examples/examples/z_bytes.rs
• C (zenoh-c) Add z_bytes example zenoh-c#687 add z_bytes example zenoh-c#708 @DenisBiryukov91 @milyin
• C (zenoh-pico) Add z_bytes example zenoh-pico#662 Add z_bytes example zenoh-pico#673 @sashacmc @jean-roland
• C++ Add z_bytes example zenoh-cpp#216 z_bytes example zenoh-cpp#218 @DenisBiryukov91 @yellowhatter
• Python Add z_bytes example zenoh-python#318 docs: add z_bytes example zenoh-python#325 @wyfo
• Kotlin Add z_bytes example zenoh-kotlin#219 @DariusIMP

Protobuf example:

• Rust

  zenoh/examples/examples/z_bytes.rs

  Line 154 in ddcc8f1
