[Koha] 21.05 update: link from staff interface biblio to OPAC

[Elaine Bradtke]

More a caution than a problem.  If you've been running Koha for a long
time,  the OPACBaseURL may  be "http", rather than https.
Our test OPAC requires a user login.  The link between a biblio record and
the OPAC won't work if the OPACBaseURL says http and the actual url is
https.  The logins keep failing.
Luckily it's an easy fix.
