Consider 'cargo yank'

Hi,

GNOME Security received the following issue report regarding this repo:

libolm should not be used anymore - matrix deprecated it as it was attracting CVEs and it was never supposed to be used in production - they re-wrote it in Rust two years ago

https://gitlab.matrix.org/matrix-org/olm/-/blob/master/lib/crypto-algorithms/README.md

Affected repo: https://gitlab.gnome.org/BrainBlasted/olm-sys

https://crates.io/crates/olm-sys & https://crates.io/crates/olm-rs

Please consider using cargo yank on those crates so nobody uses it

Soatok has some refined details: https://soatok.blog/2024/08/14/security-issues-in-matrixs-olm-library/
