Year typo and wrong answer

- In the page "https://ohjelmointi-26.mooc.fi/osa-4/1-vscode" there is a recommendation to select the course 'Ohjelmoinnin MOOC 2025'. It should be 2026.
- In the section "Kysely: Kertaus - osa 4.2" there is a wrong answer in "Valitse seuraavista lausekkeista ne, joiden tyyppi on bool. Valitse kaikki sopivat vaihtoehdot". **The backend states that "2" > "1" is not a type bool even though it is.**
