Prepare v0.0.21 release

Prepare a new release for `v0.0.21`, with the most important change
contained being #217, which fixes a bug in the leadership election code.

I know I said I'd switch to minor version releases after `v0.0.20`, but
since this version is largely a hotfix with a small change, I did
another patch.

 ### Changed
 
 - Tweaked behavior of `JobRetry` so that it does actually update the `ScheduledAt` time of the job in all cases where the job is actually being rescheduled. As before, jobs which are already available with a past `ScheduledAt` will not be touched by this query so that they retain their place in line. [PR #211](https://github.com/riverqueue/river/pull/211).
