build(deps): update dnspython requirement from ~=2.2.1 to ~=2.3.0

[dependabot]

Updates the requirements on dnspython to permit the latest version.

Changelog

Sourced from dnspython's changelog.

2.3.0

• Python 3.7 or newer is required.

• Type annotations are now integrated with the source code and cover far more of the library.

• The get_soa() method has been added to dns.zone.Zone.

• The minimum TLS version is now 1.2.

• EDNS padding is now supported. Messages with EDNS enabled and with a non-zero pad option will be automatically padded appropriately when converted to wire format.

• dns.zone.from_text() and dns.zone.from_file() now have an allow_directives parameter to allow finer control over how directives in zonefiles are processed.

• A preliminary implementation of DNS-over-QUIC has been added, and will be available if the aioquic library is present. See dns.query.quic(), dns.asyncquery.quic(), and examples/doq.py for more info. This API is subject to change in future releases. For asynchronous I/O, both asyncio and Trio are supported, but Curio is not.

• DNSSEC signing support has been added to the dns.dnssec module, along with a number of functions to help generate DS, CDS, and CDNSKEY RRsets. Thank you very much Jakob Schlyter!

• Curio asynchronous I/O support is deprecated as of this release and will be removed in a future release.

• The resolver object's nameserver field is planned to become a property in dnspython 2.4. Writing to this field other than by direct assignment is deprecated, and so is depending on the mutability and form of the iterable returned when it is read.

2.2.1

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

• dns.zone.from_text failed if relativize was False and an origin was specified in the parameters.

• A number of types permitted an empty "rest of the rdata".

• L32, L64, LP, and NID were missing from dns/rdtypes/ANY/init.py

... (truncated)
