DownloadCargoBinaryFromGitHub: Find most recent release with assets (#410)

Currently, the `cargo-binstall` most recent release in the binstall repo
does not actually have the binstall binary. This change allows the
search to find the most recent release that has the expected binaries to
handle the case when other releases might also be in release list that
do not have the expected binaries.
