Port is not getting added in realm when authenticating with Steam

[MJPetermann]

Hey there,
while trying to get the login with steam to work, I stumbled upon a bug, when hosting on localhost.

If your nuxt is hosted on e.g. port 3000 it causes Steam to throw a 403 Access Denied error. This happens because the realm doesn't include the port. It is easily fixed by changing the setting of the realm:
"openid.realm": `${url.protocol}//${url.hostname}:${url.port}`,
in https://github.com/atinux/nuxt-auth-utils/blob/main/src/runtime/server/lib/oauth/steam.ts

Hope this gets fixed, but till then that's the workaround :)
