chore(deps): Drop patch to use custom chrono repo (vectordotdev#18567)

We had set up a custom `chrono` repo to be able to use the crate without
enabling the `oldtime` feature, which in turn pulled in the `time` crate that
was the subject of a vulnerability issue. With the latest `chrono` release, it
no longer depends on the `time` crate, so the patch is no longer needed.
