Babel 12.2.x test failures due to no-breaking spaces and slightly different output

[hroncok]

Environment

Python Version: 3.11.2

Nikola Version: 8.2.3

Operating System: Fedora Linux 39

Description:

Hello, in Fedora we are updating our babel to 12.2.0 and I noticed some test failures of nikola. Unfortunately, I won't be able to provide a full producer as I run the tests in the Fedora package and I do not maintain that package. This is just a friendly heads-up for you, I don't expect you to do anything.

The test failures are

Apart from the at vs , change, there is also a difference in SPACE vs. NARROW NO-BREAK SPACE before PM.
