fix: Slovenian and Lithuanian plural forms

The Slovenian plural formula follows gettext and maps n%100 == 1 to
index 1, 2 to index 2, 3-4 to index 3 and everything else to index
0. The translations were stored singular first, so all plural arrays
in sl.json were rotated right by one. Two "other" forms, for the
minutes and hours expiration messages, contained the 3-4 form and
were corrected to "minut" and "ur".

The Lithuanian formula lacked parentheses around the last two digits
check, so due to operator precedence numbers like 20, 30 or 120
selected the "few" form instead of "many". Fixed in both PHP and JS,
with tests added and the SRI hash of privatebin.js updated.

 ## 2.1.1 (not yet released)
 * FIXED: Creating a document failed with a JavaScript error when the `discussion` or `password` option is disabled, as the top navigation accessed the omitted elements
+* FIXED: Slovenian plural forms were stored in the wrong order, i.e. "1 uri" instead of "1 ura" for one hour (#1951)
+* FIXED: Lithuanian plural formula selected the "few" form for numbers ending in 0 above 10, i.e. "20 sekundės" instead of "20 sekundžių" (#1956)
 
 ## 2.1.0 (2026-10-18)
 * ADDED: Added `shortenviachhoto` endpoint with an `chhoto` configuration section
