Subject: [PATCH] bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453)
 (GH-31472)

Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.

libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.

- https://www.w3.org/TR/xml-names/

Also, test_minidom.py: Support Expat >=2.4.5
(cherry picked from commit 2cae93832f46b245847bdc252456ddf7742ef45e)
