chore: (cargo serde example)

[mrceperka]

Example that uses Serde as a Rust dependency and returns serialized (JSON) struct.

Hello, thanks for the new example! I'm happy you've been able to use Rust with Serde to encode your data with JSON, and decode them in PHP.

However, I don't see how it illustrates php-ext-wasm. The API usage is almost identical to the greet example. Your example shows the pre-Wasm part (in this case, the Rust part), and not the PHP part (which is the goal of the examples/ directory: it shows how to use the PHP Wasm extension). Wasm is not tied to Rust only, but to any language that can compile to Wasm, so adding an illustration with Rust isn't clear for me. It has its place as a blog post though!

What do you think?

I don't think that I am able to write a blog post. You can of course reuse this material and PR.

Also, you are right, this does not illustrate new usage of php-ext-wasm.

Feel free to close this PR.
Thanks for you reaction.
