Currently 'ru' and 'zh-tw' versions of website have translations of the events to corresponding languages, but home page of the website shows events list in English (it takes information from data/en/events). The code to check local version exists, but it checks the existence of events.toml file instead of events2025.toml (if 2025 is current year).
This patch fixes this issue.
Similar issue with the list of the press entries. Only difference - zh-tw has file with translations, but this file is outdated, and zh-tw site uses English version anyway. The proposal to use explicit list of languages (in addition to EN), that have local translation ('ru' and 'fr' added to demonstrate the list behavior, even if 'fr' does not have active website now).
