RUSTSEC-2025-0134: `rustls-pemfile` is no longer maintained

[Wiezzel]

Description

https://rustsec.org/advisories/RUSTSEC-2025-0134

rustls-pemfile is indirectly required by rust-s3:

rustls-pemfile 1.0.4                                                                                                                                                  
└── reqwest 0.11.27
    └── rust-s3 0.32.3

We cannot update rust-s3 to a newer version though, because newer versions of rust-s3 require Rust 1.88.

This can be resolved when the project updates to Rust 1.88
