Subject: [PATCH] swig: Add missing %template for
 std::vector<TransactionPersistence>

MergedTransaction::listPersistences() returns std::vector<TransactionPersistence>,
but no SWIG %template was declared for this type. Without it, SWIG wraps the
return value as an opaque pointer instead of a Python list, causing memory leak
warnings and preventing Python code from iterating over the values.

Add the missing template, matching the existing TransactionStateVector pattern.

For: https://github.com/rpm-software-management/libdnf/issues/1744
