Note:
Psalm throws an error:

Error: src/Extension/DateExtension.php:0:0: UnusedBaselineEntry: Baseline for issue "UndefinedFunction" has 2 extra entries. (see
https://psalm.dev/316)

We can merge this PR because it does not break anything.

I created a new issue #46 that will fix the error reported.
