fix(go/adbc/driver/flightsql): Have GetTableSchema check for table name match instead of the first schema it receives

[ywc88]

Fixes #934.

just a nit pick and then I agree with @lidavidm's comment https://github.com/apache/arrow-adbc/pull/980/files#r1301629823

BTW @zeroshade, one thing I noticed while debugging this PR:

https://github.com/apache/arrow/blob/702e9cae138e8d372643e3545375d8fc4c6212a2/go/arrow/flight/flightsql/server.go#L832-L842

	for chunk := range cc {
		if chunk.Err != nil {
			return chunk.Err
		}

		wr.SetFlightDescriptor(chunk.Desc)
		if err = wr.WriteWithAppMetadata(chunk.Data, chunk.AppMetadata); err != nil {
			return err
		}
		chunk.Data.Release()
	}

Shouldn't we release chunk.Data in both branches of the if?
