Getting "Index was outside the bounds of the array" exception when publishing to Redis stream using StreamAddAsync with StreamTrimMode.Acknowledged. The same code works fine with StreamTrimMode.KeepReference.

Environment:

• StackExchange.Redis version: 2.8.58
• .NET version: .NET 5.0
• Redis server version: 8.2.0 (running on Docker)

Code that fails:

await database.StreamAddAsync(
    streamName,
    maxLength: maxLength,
    useApproximateMaxLength: true, 
    trimMode: StreamTrimMode.Acknowledged,  // Throws exception
    streamPairs: nameValueEntries);

Code that works:

await database.StreamAddAsync(
    streamName,
    maxLength: maxLength,
    useApproximateMaxLength: true, 
    trimMode: StreamTrimMode.KeepReference,  // Works fine
    streamPairs: nameValueEntries);

Stack Trace:

Index was outside the bounds of the array.
   at StackExchange.Redis.RedisDatabase.GetStreamAddMessage(RedisKey key, RedisValue entryId, Nullable`1 maxLength, Boolean useApproximateMaxLength, NameValueEntry[] streamPairs, Nullable`1 limit, StreamTrimMode mode, CommandFlags flags)
   at StackExchange.Redis.RedisDatabase.StreamAddAsync(RedisKey key, NameValueEntry[] streamPairs, ...)

Expected behavior: StreamTrimMode.Acknowledged should work without throwing array bounds exceptions.
