generate-logictest: add test timeout to BUILD files template

In #86363, we added a test.timeout arg to all go_test targets.
When generate-logictest runs out of `bazel-generate.sh`,
logic tests build files are re-created based on the template
that was missing the `test.timeout` arg. This patch updates
the template to include a test timeout.

Release justification: Non-production code changes
Release note: None
