Bug 32229: Typo: Items missing from bundle at checking for %s

This patch corrects a typo in the missing items from bundle pop-up
header.

To test:

I created a MARC21 file of records to use as an example. It assumes
you have the sample branches and itemtypes that come with Koha. You
can use any record you have in your database, you need at least three
records each with at least one item.

0. Apply patch
1. If using the example records, import the records
   1.1. Download the attached earlyliteracy.mrc file
   1.2. Go to Cataloging > Stage records for import
   1.3. Click the button and select the file on your computer
   1.4. Click 'Upload file'
   1.5. Click 'Stage for import'
   1.6. Click 'View detail of the enqueued job'
   1.7. Click 'View batch'
   1.8. Click 'Import this batch into the catalog'
2. If using the example records, bundle the books into the 'My first
books bundle' record
   2.1. Click 'Manage imported batch'
   2.2. Click 'View' next to 'My first books bundle'
   2.3. Click 'Manage bundle' on the right of the item
   2.4. Click 'Add to bundle'
   2.5. Enter the following barcodes, followed by 'Submit' (or press
enter) after each
        -  001229
        -  001230
        -  001231
        -  001232
        -  001233
   2.6. Click 'Close'

Alternate step 2, if using own records: find a record with an item,
change the leader/position 7 to c, click 'Manage bundle', then 'Add
to bundle' and enter a few existing barcodes (at least 2).

3. Check out bundle
   3.1. Go to Patrons
   3.2. Click 'Search' to find a patron
   3.3. Click 'Checkout' next to a patron
   3.4. If using example records, enter the following barcode into the
checkout box and click 'Checkout' (or press enter)
        -  001234
        Alternate step 3.4, if using own records: checkout the 'main'
record in which you bundled all the other records

4. Check in bundle, 'losing' at least one item
   4.1. In the bar at the top of the screen, select 'Check in'
   4.2. If using the example records, enter the following barcode and
click the arrow (or press enter)
        -  001234
        Alternate step 4.2, check in the same barcode you just checked
out
   4.3. In the 'Barcodes' box, enter the following barcodes, pressing
enter between each
        -  001229
        -  001230
        -  001231
        Alternate step 4.3, enter only some of the bundled barcodes
   4.4. Click 'Confirm checkin and mark missing items as lost'
   4.5. Click 'View list of missing items'
        --> Items missing from bundle at checkin for (barcode)
