This avoids action conflicts when testonly non-test targets depend on test targets.

Until --incompatible_check_testonly_for_output_files is flipped, it is still possible to get action conflicts when a non-testonly target depends on an output file of a test. Since this can be fixed by adding the missing testonly annotation, this is only a minor concern.

Fixes #28056

Closes #28073.

This avoids action conflicts when `testonly` non-test targets depend on test targets.

Until `--incompatible_check_testonly_for_output_files` is flipped, it is still possible to get action conflicts when a non-`testonly` target depends on an output file of a test. Since this can be fixed by adding the missing `testonly` annotation, this is only a minor concern.

Fixes bazelbuild#28056

Closes bazelbuild#28073.

Code Review

This pull request changes the default value of the experimental_retain_test_configuration_across_testonly flag to true. This is intended to mitigate action conflicts when testonly non-test targets depend on test targets. The change is straightforward and seems appropriate for an experimental flag that is moving towards being enabled by default. The provided tests appear to cover the behavior with the new default.
