BSD-2-Clause license header missing from source files in latest release (0.64.8)

[PathanTauheedKhan]

Hi @vsch
We are using flexmark-all version 0.64.8 (latest available on Maven Central) and noticed that the BSD-2-Clause license header is missing from certain source files.

Specifically, the following file does not contain the BSD-2-Clause license header:
https://github.com/vsch/flexmark-java/blob/4aac7f94967a1f8ea449a0738deae27554747707/flexmark-util-collection/src/main/java/com/vladsch/flexmark/util/collection/iteration/ArrayIterable.java

We noticed from issue #443 that this was marked as resolved in August 2023, however the commit that adds the BSD-2-Clause license header does not appear to belong to any branch in this repository.

Could you please clarify:

1. Will a new release be published that includes the BSD-2-Clause license header
   in all source files?
2. Is there a specific branch or commit we can reference that contains this fix?
3. Is there any other way to obtain or reference the updated file with the
   correct license header included?

Thank you for your time and support.
