chore: edit www helper

[jhKessler]

Changes

• Changed the Project-Resource helper text to include notice that the user also needs to add the www. domain under the domains section.

I wanted to handle www domains, but didn't read every tooltip and thus thought that coolify will automatically add the www domain through my wildcard domain setup, and redirect to my application. I think it would be nice to add the extra sentence "Make sure the www domain is added under Domains." under the "Direction" helper text, so that other people like me know they need to add www to the domains section.
