[dependabot]

Updates the requirements on dnspython to permit the latest version.

Changelog

Sourced from dnspython's changelog.

2.2.1

This release has no new features, but fixes the following issues:

• Timeout intervals are no longer reported with absurd precision in exception text.

• SVCB and HTTPS records have been updated to track the evolving draft standard.

• The ZONEMD type has been added.

• The resolver now returns a LifetimeTimeout exception which includes an error trace like the NoNameservers exception. This class is a subclass of dns.exception.Timeout for backwards compatibility.

• dns.zonefile.read_rrsets() has been added, which allows rrsets in zonefile format, or a restrition of it, to be read. This function is useful for applications that want to read DNS data in text format, but do not want to use a Zone.

• On Windows systems, if the WMI module is available, the resolver will retrieve
