Tests: Adapt expected traceback regexes for Python 3.11.0a1

[hroncok]

Fixes #1526

Before:

  File ".../broken.html", line 2, in <module>
    {{ fail() }}
  File ".../test_debug.py", line 32, in <lambda>
    tmpl.render(fail=lambda: 1 / 0)
ZeroDivisionError: division by zero

After:

  File ".../broken.html", line 2, in <module>
    {{ fail() }}
    ^^^^^^^^^^^^
  File ".../test_debug.py", line 32, in <lambda>
    tmpl.render(fail=lambda: 1 / 0)
                             ~~^~~
ZeroDivisionError: division by zero

It made all the previously succeeded CI jobs fail with GitHub Actions has encountered an internal error when running your job.

Looks like some problem on GitHub's side. I restarted the CI run and it's fine now. But I think we need to update our CI config to test against 3.10 and 3.11 as well...
