EnhancedDynamoDB#AutoGeneratedUuidExtension with supplier UUID

### Describe the feature

Possibility of setting a supplier to generate the UUID, thus making it compatible with generating other versions of UUID such as v7

### Use Case

I need a UUID with TimeStamp as version 7, but the AutoGeneratedUuidExtension is stuck with UUID.randomUUID() which only generates version 4.

### Proposed Solution

Evolve the extension to accept a supplier or use the standard UUID.randomUUID().
