OpenAPI version field not being set.

[luisjones]

Currently https://papermc.io/api/openapi returns "info":{"title":"PaperMC API"}. This causes the OpenAPI generator I am attempting to use to fail, as it is missing the key version that is a required field (see https://swagger.io/specification/v3/#info-object)

I can see that this was resolved in #156/#157/#158, although this value still does not seem to be set. I am unsure as to where the configuration for this application lives, but is it possible app.ApiVersion isn't being passed as a command line argument/environmental variable following this change?
