10130/feature/stripping leading and trailing whitespaces from form input

[Spaarsh]

Closes #10130

feature

Technical

The implementation deals solely with changes in the frontend JavaScript for the add.html and edit.html pages.

Testing

The PR affects the pages required for adding a new book, editing an existing edition and adding a new edition to existing book.

1. Opening the page

   • Adding a New Book - go to the bottom of the home page and click on the "Add a new book" option.
   • Editing the edition of a book - visit any book's page and click on the "Edit" button on the top right.
   • Adding a new edition of a book - visit any book's page and scroll down to the editions table and click on the "Add another edition?" option.

2. Fill any of the input fields while intentionally adding leading and/or trailing white-spaces, and deselect the field.

3. If the leading and trailing white-spaces disappear, the intended behavior has been achieved.
