api/Cargo.lock: bump

This is necessary due to an outdated `time` crate causing a build
failure on Rust 1.80.0 and later.

To reproduce these changes, run the following commands:
```
<clone my fork>
cd api
mv Cargo.lock Cargo.lock.bak
cargo update
diff Cargo.lock Cargo.lock.bak
-- There should be no changes, assuming that new updates to your
-- dependencies exist.
```
