Bug 26665: (bug 20168 follow-up) Fix path to bootstrap js file

20168 moved it to /opac-tmpl/bootstrap/lib/bootstrap/js/bootstrap.bundle.min.js

It fixed the OAI-PMH view

Test plan:
Hit <OPACBaseURL>/cgi-bin/koha/oai.pl?verb=ListRecords&metadataPrefix=marc21
and confirm that you can click "Metadata" and it opens
