Restore explicit version requirement on 1.3 HelloRetryRequest tests
Restore explicit version requirement on 1.3 HelloRetryRequest tests

A concurrent branch changes the way the test cases run to no longer use
force_version=tls13, so the automatic version requirement detection will no
longer work after that branch is merged. Therefore, keep the manual
requirement (at least until automatic detection gets smarter).
