Remove info banner from Team details > Agent options

The `overrides` section was removed from the default agent options in "Add fleetctl and Fleet UI support for remote flags" #7377:
> When there is no overrides being specified by the user, do not show a blank overrides section

- Remove the info banner that links to help with `overrides` because a new Fleet user won't understand what the `overrides` section is.
