Steps to reproduce:
1. Enable Update Supprot for SI: https://liferay.dev/blogs/-/blogs/site-initializers-update-support
2. Define Layouts for Segment Experiences in SI module.
3. Deploy SI module, and create a site from SI.
4. Run Syncronize.
Expected behavior: everything stays the same if no
changes were made to SI
Actual behavior: segment experiences are duplicated.
Reason: BundleSiteInitializer._addSegmentsExperiences
method is not deisgned for update support.
