[Certbot-dev] Certbot 2.2.0 Release

[Brad Warren]

Certbot 2.2.0 has just been released. The changelog for the release is:

## 2.2.0 - 2023-01-11

### Changed

* Certbot will no longer respect very long challenge polling intervals, which may be suggested
  by some ACME servers. Certbot will continue to wait up to 90 seconds by default, or up to a
  total of 30 minutes if requested by the server via `Retry-After`.

More details about these changes can be found on our GitHub repo.
