[FIX] test_new_api: mitigate babel issue

Since Babel issue 621 [0] searching the week number of a date alongside
with the year can lead to a wrong year in the result. e.g.: `2023-01-01`
gives `W1 2022`

Before the present commit, the tests were surprisingly expecting the
wrong result.

An attempt was made [1] to fix the upstream issue but was never merged.

In the meanwhile, Debian reverted the Babel issue 621 [2] in their
package.

It means that our test would fail with the patched Debian package like
in Ubuntu Noble or Debian Bookworm. On the other hand, if we fix the
test to expect the correct value, it would fail on unpatched version of
the Babel lib.

So, this commit mitigate the issue by guessing the expected value even
if the result is wrong.
