fix: Fix dates parsing on news listing/displaying (#229)

Archweb recently switched date format from `01-01-2024` to `Jan. 01, 2024`, breaking the date parsing during the Arch news listing/displaying.
This commit updates the date parsing accordingly to fix the "invalid date" error during the news listing and the incorrect "Author/Date" fields when displaying a news.
