🐛 Fixed usage of plural in game_not_started page

[Proxyfil]

🎩 What? Why?

This PR changes the behaviour of the page game_not_started for the admin to actually update text when there is 0, 1 or multiple players.

The previous code was not using this, and thus, was never displaying the plural when needed.
Now for 0 or 1 it will be "player" and for more it will be "players", it should also be accurate in every translations because the text key was already in here.

I suggest now in another PR to fix the mistranslation (like in english "are waiting" for not plural or in french "joueurs sont en")
