Binding name should be treated case-insensitive

[varuntechie]

What I Did
My codes:
stmt, _ := tx.PrepareContext(ctx, "/cmd/insert into test_simple_table_2 (accountID, Name, Status) VALUES(:accountID, :Name, :Status)")
_, err = stmt.Exec(sql.Named("accountID", "12345"), sql.Named("Name", "Steve"), sql.Named("status", "done"))

What I Expected
The above codes have ":Status" in PrepareContext and "status" (lower case) in stmt.Exec
I expect Hera to do case-insensitive matching check for binding name, query should be executed successfully

What I Saw Instead
Error: bindname not found in query: :status - processing 2 8:2 status,

Here is log:

Or when changing case for binding name from :accountID to AccountID, I get this error:
14:55:15.571877 debug: [WORKER shd3 0 cmdprocessor.go:173] process command 11:2 AccountID,

We are inconsistent. For shard key name matching, we do case insensitive check, isShardKey https://github.com/paypal/hera/blob/af6bc1d04dfc16241f851ef25ca925df1cd839a8/lib/coordinatorsharding.go#L261C1-L274C44
