Bug 34565: Label mismatch in MARC21 006 and 008 cataloging plugins

This patch modifies the JS which builds the table of options for
populating MARC21 fields 006 and 008 when using the cataloging plugin.

To test, apply the patch and go to Cataloging -> New record.

- Click the plugin trigger link next to the 006 input field (you may
  need to click the tag to expand it.
- In the table of input fields, test that clicking the label, e.g. "Type
  of material", "00 - Form of material," etc,  moves focus to the
  corresponding form field.
- Perform the same test on the plugin-popup for field 008.
