Bug 40081: Textareas should resize horizontally and vertically

Bootstrap 5 sets the "resize" property on textareas to "vertical." For
our purposes this is a regression in functionality and should be
overridden.

To test, apply the patch and rebuild OPAC and staff interface CSS.

- Log into the OPAC and go to the "Your personal details" page.
  - Under "Alternate address" -> "Contact note," check that the textarea
    can be freely resized.
- In the staff client, create a new patron and test the same textarea in
  that form.
