Adding statsig_elixir to a mix project and deploying on a bookworm slim based Dockerfile crashes at startup with Failed to load NIF ... 'libssl.so.1.1: cannot open shared object file'. The prebuilt NIF binary was linked against OpenSSL 1.1, which slim Debian images do not ship.

The Statsig team released a fixed build, statsig_elixir 0.7.4-beta.2508150240, which runs on all Linux and mac systems regardless of the OpenSSL version in the image. Bump the dependency to that version or later.
