fix(nextcloud): drop obsolete UserConfig::getValueBool patch

The nextcloud/server#59629 TypeError workaround (PR #59646) is no longer
needed once nextcloud_image is >= 33.0.4, which now ships the fix.
Remove the in-container sed patch task, its container-discovery and
drift-guard tasks, and the README note.

-# nextcloud/server#59629: UserConfig::getValueBool() passes a non-string from
-# getTypedValue() into strtolower() under PHP 8.x + OPcache, throwing a
-# TypeError on every authenticated request once user_ldap is involved. Fix
-# is in master (PR #59646) but no stable33 backport landed before 33.0.4.
-# Apply the (string) cast in-container; idempotent via grep guard. Remove
-# this block once nextcloud_image >= 33.0.4.
