Babel's named / implicit formats (short, medium, long, ...) come from
the CLDR, which can get tuned as debates get settled, cultures shift,
etc... as a result using these formats can break tests on any babel or
even CLDR release (technically nothing stops distros from updating
their bundled babel with new CLDR data).
b77eb98bbf6bc937efb7941802c0794ae3622094 previously did some
mitigation of this issue, but even if they're not yet in distros
further Babel updates (e.g. 2.12) already affect some of the patterns
we're using.
Proactively mitigate this issue more by only using explicit datetime
patterns (and time patterns, date is fine because it retrieves the
pattern from the lang rather than default to babel patterns) in the
date/time formatting tests. This means only specific terms still vary,
and those should be a lot more stable / reliable than e.g. futzing
with separators and minor formatting issues.
