Package installation doesn't work anymore:

Do I need to install some ssl library? I'm on fedora 45.

Fedora 45 uses OpenSSL version 4, and Racket only searches for OpenSSL shared libraries with version suffix up through 3 (eg, `libssl.so.3`). We need to fix that.

The quickest workaround, I believe, is to install the `openssl3-libs` compatibility package.
