[PR] [core] Fix scan version for fallback branch [paimon]

["ArnavBalyan (via GitHub)" <gi...@apache.org>]

ArnavBalyan opened a new pull request, #9323:
URL: https://github.com/apache/paimon/pull/9323

   ### Purpose
   - During reads, when a fallback branch is configured, Paimon forwards the scan.version to the fallback reader.
   - However this scan version can represent different commit timestamps across the main and fallback branch causing the wrong snapshot to be picked from fallback branch.
   - Fix by mapping scan versions to the fallback snapshot using the main snapshot timestamp.
   
   ### Tests
    - UT
