Hi!  Building `python-zope-exceptions` 4.4 fails in the version of Guix shown below:

```
$ LANG=C guix describe
Generation 56   May 02 2023 11:25:26    (current)
  guix 3f8c489
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 3f8c4899a9a67bb509a603bd21dcfcfab88c0e8e
```

It looks like a Python 3.10 issue fixed in a newer upstream version.  This is
the final part of the build log:

```
starting phase `check'
Running zope.testrunner.layer.UnitTests tests:
  Set up zope.testrunner.layer.UnitTests in 0.000 seconds.

Failure in test test_multiline_exception (zope.exceptions.tests.test_exceptionformatter.Test_format_exception)

AssertionError: False is not true
```

Looking at the failing line, it looks like the commit below fixed it for
Python 3.10 compatibility:
<https://github.com/zopefoundation/zope.exceptions/commit/cb2d21400c95b73909b1145674c08fed31b8759a>

Probably version >= 4.5 of the package (which claims "Add official support for
Python 3.9 and 3.10." does work (I've been unable to figure out the proper
`--with-XXXX` incantation to assert that).

Thanks!
