Incorrect note about tenant field on application

[mooreds]

This link: https://fusionauth.io/docs/get-started/core-concepts/applications#add-an-application

Says this about the tenant field when the application is created.

The tenant in which to create this Application.

This field is only displayed once multiple tenants exist in FusionAuth. When only a single tenant exists, the Application will always be created in the default tenant.

But we show the field whether or not there is only one tenant right now (as of 1.60.0). I'm not sure when this behavior was introduced.

We should either adjust the doc or check with engineering to see if this is a regression from expected behavior.
