build: use statically linked libssl

[therapon]

We build our binaries on ubuntu:20 which uses libssl1.1 (through our direct dependency of reqwest). Libssl is dynamically linked and with systems moving to ubuntu:22 that has libssl3.0 our binary breaks. An example is Google's Collab.

We also build multiplatform linux docker image using cross-rs. cross-rs currently builds for ubuntu:20 on their master branch and there is currently an open PR (cross-rs/cross#973) to move to ubuntu:22.

The proposed solution with this PR is to enable the feature on reqwest that builds the libssl crate (and the libssl library) statically in the sparrow binaries rather than relying on dynamic linking to pick the system's libssl library.

We are not moving our CI to use ubuntu:22 until there we have a solution for building multiarch images on ubuntu:22 (through cross-rs or otherwise). Otherwise, if we move to ubuntu:22 today with out any other changes our docker image will break on linux on arm (anyone on a Mac with an M chip running a docker container).

1. sparrow depends on reqwest which brings in libssl.
2. added an if condition on the release CI that we missed

I verified that the binaries

Before:

❯ ldd sparrow-main
	linux-vdso.so.1 (0x00007fff56643000)
	libssl.so.3 => /lib/x86_64-linux-gnu/libssl.so.3 (0x00007f3387ee8000)
	libcrypto.so.3 => /lib/x86_64-linux-gnu/libcrypto.so.3 (0x00007f3383e00000)
	libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f3383a00000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f3387ec8000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f398d9dd000)

The final release binary size increases by 2MB

I think so too. Was going to commit, release and verify before closing the issue.
