There are currently a few places where a user is suggested to contact the administrator of the Matomo instance. In most cases there is a
mailto link that contains the email addresses of all super users.
In some scenarios it might be unexpected that in this places the (possibly private) mail addresses are disclosed.
To avoid this, this PR introduces as new config setting to set a contact email address, that will be used for those links instead.
By default this config setting isn't set and it falls back to use all super users emails.
In companies for example it might be more helpful to send an email to a support mailbox instead of sending an email to some specific persons.
As the author of the mail to email@example.com, that lead to this PR, I just wanted to say thank you. And I hope that the build and Merge Issues can be fixed
