Missing OpenSSL in aarch64

An old Dockerfile contains openssl code but the latest Dockerfile only sets AARCH64_UNKNOWN_LINUX_GNU_OPENSSL_DIR.

Does ghcr.io/rust-cross/manylinux2014-cross:aarch64 intend to come with openssl installed?
I couldn't find the installation so manually installed and overwrite AARCH64_UNKNOWN_LINUX_GNU_OPENSSL_DIR.

This AARCH64_UNKNOWN_LINUX_GNU_OPENSSL_DIR is picked up before OPENSSL_DIR or pkg-config by openssl-sys, so I had to set AARCH64_.._LIB_DIR and AARCH64_.._INCLUDE_DIR.

            apt-get install -y libssl-dev:arm64
