Shift language away from calling all entries 'games'

[Isquiesque]

I thought we had already adjusted this language on the IFComp site, and we have in several places (as in Browse and play this year's entries, and then rate them), but we do still have some prominent areas where we say things like The games of the 2025 Interactive Fiction Competition are ready for judging! or play and rate at least five games.

I have generally tried to be intentional in blog posts and such to use the term 'entries' because some entries are not exactly games, and it would be good to use more neutral/inclusive language throughout the site. We of course welcome games, but we also welcome stories and other types of entries.
