Improve devise error_message

What does this MR do and why?

As a first iteration of #384351, this MR improves error messages UI by using Pajamas Alert component.

done:

• Add devise/shared/error_messages in the project, instead of using the one from devise gems : https://github.com/heartcombo/devise/blob/main/app/views/devise/shared/_error_messages.html.erb
• Convert the erb to haml
• Use Pajamas::AlertComponent.new instead of pure HTML list

This change will affect:

• app/views/devise/confirmations/new.html.haml
• app/views/devise/passwords/edit.html.haml
• app/views/devise/passwords/new.html.haml
• app/views/devise/registrations/edit.html.erb
• app/views/devise/shared/_signup_box.html.haml
• app/views/devise/unlocks/new.html.haml
• app/views/registrations/welcome/show.html.haml
