Autosubmit does not warn the user when using a valid extended header/tailer on a "none" project

This is just an issue to remember ourselves (@mgimenez and I) to add a message when a specific situation occurs using an extended header/tailer.

Autosubmit Version

Any version of Autosubmit 4, but also Autosubmit 3.15 is susceptible to.

Summary

When using an extended header or tailer, but the project is of type "none", Autosubmit should throw a message notifying that the script is valid but the project's type is not, and it must be changed (to "local", for example). This would be useful for cases in which someone is building an experiment from scratch but doesn't know about project types, like me (discovering the reason because the extended header was not being included in the cmd files of my experiment was a true headache :)

Steps to reproduce

Just create a new experiment and add a custom header without changing the project type.

What is the current behavior?

Autosubmit runs the experiment without warning the user.

What is the expected correct behavior?

Autosubmit should warn about it. It is a small fix that would be useful both for beginners and experimented developers with little auto-modelling knowledge.
