RUSTSEC-2025-0134: rustls-pemfile is unmaintained

| Details | | | --- | --- | | Package | `rustls-pemfile` | | Version | `2.2.0` | | Warning | unmaintained | | URL | https://github.com/rustls/pemfile/issues/61 | | Patched Versions | n/a | The rustls-pemfile crate is no longer maintained. The repository has been archived since August 2025, and users are encouraged to depend directly on the underlying PEM parsing code included in rustls-pki-types since 1.9.0. The latest version of rustls-pemfile is in fact a thin wrapper around the same code used in rustls-pki-types, so migrating should be straightforward. The new API is represented by the [`PemObject`][PemObject] trait, which provides methods for reading a single or multiple PEM objects from a file or byte slice.
