The "Add new code component" modal should save by pressing Enter

Made the requested changes.

I tested this issue on my local setup. Before checking out this branch, pressing Enter in the 'Add new code component' modal was not submitting the form, and I had to manually click the 'Add' button.
After switching to the issue branch, I verified that pressing Enter now successfully submits the form without needing to click the button.
