Slovenian localized formats not by standard

**Describe the bug**
When dayjs is set to Slovenian locale and when localized format strings are used for formatting, the displayed date is wrong.
Looking at the locale file, L is set to "DD.MM.YYYY" instead of "D. M. YYYY".

**Expected behavior**
L format in Slovenian locale should display date as 24. 5. 1992. So day and month should never prepend "0" and space should be added after dots.

Start by locating Day.js's Slovenian locale file and the tests for localized date formats. Compare the locale's L definition with the expected Slovenian pattern described in the issue. Update the locale data and run the relevant locale or format tests to confirm that L renders the intended date.
