Display error summary at the top of the page with multiple forms

[blesildaramirez]

Description

Create a new component that provides the summary of all errors found in a single or multiple forms.
This component should:

• dynamically render error messages based on an API response containing field IDs and error messages.
• provide a summary of errors and navigable fields with errors for easier correction of the form fields with error.
• be displayed on top of the first form if the page has multiple forms.
