Fix webpki::Error trait bound issue in CI workflow

Add `webpki` and `rustls-platform-verifier` dependencies to `Cargo.toml` and implement custom error wrapper for `webpki::Error`.

* **Cargo.toml**
  - Add `webpki = "0.22"` under `[dependencies]`
  - Add `rustls-platform-verifier = "0.4"` under `[dependencies]`

* **src/main.rs**
  - Implement `std::error::Error` trait for `webpki::Error` by creating a custom error wrapper `WebPkiError`
  - Update code to use `WebPkiError` instead of `webpki::Error`
