RUSTSEC-2025-0134: `rustls-pemfile` no longer maintained

`cargo deny` shows: ``` advisory detected │ ├ ID: RUSTSEC-2025-0134 ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2025-0134 ├ The rustls-pemfile crate is no longer maintained. The repository has been archived since August 2025, and users are encouraged to depend directly on the underlying PEM parsing code included in rustls-pki-types since 1.9.0.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. [PemObject]: https://docs.rs/rustls-pki-types/latest/rustls_pki_types/pem/trait.PemObject.html ├ Announcement: https://github.com/rustls/pemfile/issues/61 ├ Solution: No safe upgrade is available! ├ rustls-pemfile v2.2.0 └── amqprs v2.1.3 ``` This is found here: ```toml # SSL/TLS dependencies tokio-rustls = { version = "0.26", optional = true, default-features = false } rustls-pemfile = { version = "2.1.2", optional = true } rustls-webpki = { version = "0.103", optional = true, default-features = false } webpki-roots = { version = "0.26", optional = true } rustls-pki-types = { version = "1.7.0", optional = true } ``` `amqprs` already depends on the recommended `rustls-pki-types`, but is using an older version than the one suggested: `1.7.0` -> `1.9.0` is needed.
