Update requirements: Bump zope-interface from 8.2 to 8.3

[dependabot]

Bumps zope-interface from 8.2 to 8.3.

Changelog

Sourced from zope-interface's changelog.

8.3 (2026-04-10)

• Add support for free-threaded Python 3.14t: declare Py_mod_gil_not_used in C extension, replace borrowed-reference PyDict_GetItem() with strong- reference PyDict_GetItemRef() in cache lookups, and use Py_TYPE() macro instead of direct ob_type struct access.

• Add CI testing for free-threaded Python 3.14t (Linux).

• Guard 4 unprotected PyErr_Clear() calls in the C extension with PyErr_ExceptionMatches checks, matching the pattern already used at 7 other sites in the same file. Without the guard, KeyboardInterrupt, MemoryError, and SystemExit are silently swallowed in implementedBy and providedBy. See issue 358 <https://github.com/zopefoundation/zope.interface/issues/358>_.
