Fix Stdlib::HTTPSUrl type name

[laugmanuel]

The datatype has to be HTTPSUrl instead of Httpsurl to not break the foreman-installer if using the params.pp directly:

[root@foreman4xng ~]# foreman-installer --scenario custom --noop --verbose
[FATAL 2020-04-02T08:01:02 fatal] Unable to continue because of: unknown data type Stdlib::Httpsurl

I'm not really sure why this works when just including the class without specifying the parameters explicitly (like in https://github.com/theforeman/puppet-katello/blob/master/manifests/init.pp#L159-163)

see https://github.com/puppetlabs/puppetlabs-stdlib#stdlibhttpsurl

The problem is that Kafo is case sensitive when it comes to types while Puppet isn't. We have https://github.com/theforeman/kafo_module_lint but don't apply this to all classes.
