diffoscope: upgrade 260 -> 265

Changelog:
==========
* Ensure that tests with ">=" version constraints actually print the
  corresponding tool name.
* Prevent odt2txt tests from always being skipped due to an impossibly new
  version requirement.
* Avoid nested parens-in-parens when printing "skipping" messages
  in the testsuite.
* Don't crash on invalid zipfiles, even if we encounter 'badness'
  halfway through the file.
* Fix a crash when there are (invalid) duplicate entries in .zip files.
* Add note when there are duplicate entries in ZIP files.
* Add an external tool reference for GNU Guix for zipdetails.
* Add support for the zipdetails(1) tool included in the Perl distribution.
* Don't use parenthesis within test "skipping" messages; PyTest adds its own
  parenthesis, so we were ending up with double nested parens.
* Fix the .epub tests after supporting zipdetails(1).
* Update copyright years and debian/tests/control.
* Fix MozillaZipContainer's monkeypatch after Python's zipfile module changed
  to detect potentially insecure overlapping entries within .zip files.
* Factor out Python version checking in test_zip.py.
* Also skip some zip tests under 3.10.14 as well; a potential regression may
  have been backported to the 3.10.x series. The underlying cause is still to
  be investigated.
* Don't crash if we encounter an .rdb file without an equivalent .rdx file.
* In addition, don't identify Redis database dumps (etc.) as GNU R database
  files based simply on their filename.
