Updated getIndexInfo() to include Columnstore indexes by using custom query.

[Ananya2]

Replaced the use of the sp_statistics stored procedure with a custom query to retrieve index information as the sp_statistics procedure did not return Columnstore indexes, so a query using sys.indexes was implemented as a workaround.
This new query ensures that all index types (Clustered, NonClustered, Columnstore) are included in the result set.
Github Issue: #2546
