Describe the solution you'd like

Since the star-tree is not feature-flagged as experimental anymore, we need to remove up @ExperimentalApi annotations across code-files across indexing and search.

Additional context

Since this change does not involves considerable logical planning, I feel this is a low-effort good first issue as well, which involves minor code change, running spotless, and raising a PR.

Contributor guide

Research direction
Find all files in the star tree related indexing and search packages that contain @ExperimentalApi annotations. Remove the annotations and ensure no imports for that annotation remain. Run `./gradlew spotlessApply` to format the code. Submit a pull request.
