Add DynamoDB Streams icon

[kakakakakku]

Hi 😀 Thank you for providing such an awesome tool!

I wanted to use the DynamoDB Streams icon, but I couldn't find it. The motivation for this pull request is to add the DynamoDB Streams icon.

Note 🗒️

AWS provides official icon sets, and the database category icons have already been redesigned to a pink-like color.
https://aws.amazon.com/architecture/icons/

However, the existing database category icons in this tool use an older version. To maintain consistency, I aligned the design with the existing icons. I found the old design on this website (note: the old design is no longer officially provided).
https://cloud-icons.onemodel.app/aws/resource_icons/res_database/res_amazon_dynamodb_stream

Check ✔️

I checked with my sample code.

with Diagram('', filename='./sample', show=False):
    table = DynamodbTable('DynamodbTable')
    item = DynamodbItem('DynamodbItem')
    streams = DynamodbStreams('DynamodbStreams')

Could you please review? Thanks a lot 👍
