This PR addresses the issue where the text_area helper is no longer functional in Rails 8 due to its renaming to textarea.

Hi @aki77 thanks for contributing! Can you please add some tests to your PR?

Thank you for your response.

Since the output of the standard text_area helper and the ViewComponent::Form::TextAreaComponent is exactly the same, I’m struggling to figure out how to write a test to verify that the ViewComponent::Form::TextAreaComponent is actually being used.

Do you have any ideas or examples of similar tests that might be helpful?

Thanks @aki77

I did a review and add a comment.
May you also do the following ?

• Rename text_area by textarea in the README
• Adding a line in the Changelog
• Do the same changes for rich_text_area

If you need I may take time to finalize the changes.

I think we may keep it at auto generate like it was. Like for phone_field and telephone_field.

And so removing the textarea method bellow, and moving the alias just after alias_method :phone_field, :telephone_field.
