[PR] Remove deprecated Operations.concatenate and union methods [lucene]

getsaurabh02 opened a new pull request, #15762:
URL: https://github.com/apache/lucene/pull/15762

   ## Title
   Remove deprecated Operations.concatenate and union methods
   
   
   ## Description
   Removes deprecated `Operations.concatenate(Automaton, Automaton)` and `Operations.union(Automaton, Automaton)` methods as suggested by @rmuir in #15750.
   
   ### Changes
   - Removed `Operations.concatenate(Automaton, Automaton)`
   - Removed `Operations.union(Automaton, Automaton)`
   - Updated CHANGES.txt
   
   ### Rationale
   These methods were deprecated in favor of the List/Collection variants and are no longer used anywhere in the codebase. The removed methods were simple wrappers that just called `concatenate(Arrays.asList(a1, a2))` and `union(Arrays.asList(a1, a2))`.
   
   ### Migration
   Users should replace:
   - `Operations.concatenate(a1, a2)` → `Operations.concatenate(List.of(a1, a2))`
   - `Operations.union(a1, a2)` → `Operations.union(List.of(a1, a2))`
   
   ### Testing
   - All core tests pass
   - No usages of the deprecated methods found in the codebase
