Provide Tasks Examples

[LeoBorai]

It would be nice to have different reusable tasks examples. So far an HTTP Example is available which allows us to send HTTP requests. Other examples like sending email or performing an API call using a dedicated client would be also beneficial.

• Support for wasm32-wasip2 is being discussed here: Support for wasm32-wasip2 seanmonstar/reqwest#2979 for reqwest, which is widely used in many HTTP clients for Rust.
