Replace rustls-native-certs with rustls-platform-verifier for enhanced security and performance

[msk]

The switch to rustls-platform-verifier presents several key benefits:

1. Improved Security and Correctness: rustls-platform-verifier takes into account the CA constraints of the OS, providing a more robust and secure approach to certificate validation.

2. Better Integration with OS Certificate Stores: This dependency offers enhanced compatibility with operating system certificate stores and enterprise CA deployments, which is crucial for our project's adaptability and reliability in different environments.

3. Revocation Support: It supports certificate revocation checks using OCSP (Online Certificate Status Protocol) and CRLs (Certificate Revocation Lists), thereby ensuring that our application remains secure against revoked certificates.

4. Reduced I/O and Memory Overhead: Unlike rustls-native-certs, rustls-platform-verifier does not require loading and parsing all platform CAs, resulting in lower I/O and memory usage.
