Fix misleading retry message when GET_SOURCES_ATTEMPTS=1

When GET_SOURCES_ATTEMPTS is set to 1 (the default), the runner would print "Retrying in 5s" even though no retry would occur. This was confusing for users.

This change ensures the retry message is only printed when there are actually more attempts remaining (i.e., attempt < attempts-1).
