Update requirements: Bump zope-interface from 8.4 to 8.5

[dependabot]

Bumps zope-interface from 8.4 to 8.5.

Changelog

Sourced from zope-interface's changelog.

8.5 (2026-05-26)

• Build and upload free-threaded (cp314t, cp315t) wheels for all platforms. Expand CI testing for free-threaded Python 3.14t from Linux-only to all platforms (macOS, Windows), and add 3.15t CI. See issue 374 <https://github.com/zopefoundation/zope.interface/issues/374>_.

• Replace all remaining PyDict_GetItem() calls in the C extension with exception-safe alternatives (PyDict_Contains, PyDict_GetItemWithError). PyDict_GetItem silently swallows exceptions from __hash__/__eq__, causing isOrExtends() to return False instead of raising TypeError for unhashable objects. Also use PyType_GetDict() on Python 3.13+ for free-threading safety when accessing the type dict. See issue 357 <https://github.com/zopefoundation/zope.interface/issues/357>_.
