DOC: configuration: corrected description of keyword tune.ssl.ocsp-update.mindelay

Deleted the text paragraph in the description of keyword
tune.ssl.ocsp-update.mindelay, which was added in the commit 5843237
"MINOR: ssl: Add global options to modify ocsp update min/max delay",
because it was a copy of the description of tune.ssl.ssl-ctx-cache-size.
