Enable tests failing due to java-joda warnings (#42693)

Tests were failing in mixed cluster after more broad warnings were introduced
in 6.x These tests were using `yyyy-MM-dd` pattern which is now warning about
the change of `y` to `u`. However, using predefined pattern
`strict_date` which uses the same format prevents the warning from being
generate and allow smooth upgrade/work in mixed cluster.
