Set specific description for ossl crate

The ossl crate's description was previously inherited from the workspace,
which is too generic.

This change provides a more specific description for the crate, making its
purpose clearer on publishing platforms like crates.io. The new description
clarifies that it provides bindings to modern OpenSSL 3+ EVP APIs.
