Subject: [PATCH] transpile: remove `git-testament` dependency (for now) to
 remove `time` dependency to build on 1.80.0

Our old nightly (1.65) pins `time-macros` to an old version, which requires `time` to stay on an old version.
But since 1.80 broke `time` (due to https://github.com/time-rs/time/issues/693 and https://github.com/rust-lang/rust/issues/127343),
we need to update `time`.  Doing this requires `time-macros` to be upgraded, which requires at least rust 1.67.
There's an old PR, #811, for this, but it needs rebasing.
So for now, removing `git-testament` and its `time` dependency is simpler,
and we can add it back later once we update to a newer nightly.
