Recent gamspy_base releases link against OpenSSL 3.2+, but the
ubuntu-latest runner ships OpenSSL 3.0.x (Ubuntu 22.04), causing
a runtime failure:
GamsException: Could not load libjoatdclib64.so:
version 'OPENSSL_3.2.0' not found
Installing openssl from conda-forge puts a new enough libssl.so.3
on the conda LD_LIBRARY_PATH before gamspy is installed, satisfying
the versioned-symbol requirement and unblocking all open PRs.

conda does not automatically add its lib dir to LD_LIBRARY_PATH, so the system linker still found the system libssl.so.3 (OpenSSL 3.0.x) first, even after installing a newer openssl from conda-forge. Exporting CONDA_PREFIX/lib at the front of LD_LIBRARY_PATH ensures the conda-forge OpenSSL (which provides OPENSSL_3.2.0) is found before the system one when gamspy loads its native shared library.
