Update the git2 crate to version 0.18.2.
Update the libgit2-sys crate to version 0.16.2.
Version 0.16.2 of the libgit2-sys crate includes an update of the bundled copy of libgit2 to version 1.7.2 to address CVE-2024-24575 and CVE-2024-24577.
Since the libgit2 bindings cause applications that use them to statically link libgit2, this update also includes rebuilds of all affected applications.
