### Description

Hi, when I try to create a Kinesis Firehose stream with destination to glue Iceberg table in a database with its name auto-generated by CFn, it throws the below validation error.

>4:23:39 PM | CREATE_FAILED | AWS::KinesisFirehose::DeliveryStream | IcebergDeliveryStreamWithCatalogA845649F
2 validation errors detected: Value at 'icebergDestinationConfiguration.destinationTableConfigurationList.1.member.destinationTableName' failed to satisfy constraint: Member must satisfy regular expression pattern: [a-zA-Z0-9\.\_]+; Value at 'icebergDestinationConfiguration.destinationTableConfigurationList.1.member.destinationDatabaseName' failed to satisfy constraint: Member must satisfy regular expression pattern: [a-zA-Z0-9\.\_]+ (Service: Firehose, Status Code: 400, Request ID: ...) (SDK Attempt Count: 1)

The generated name contains `-` (e.g. `icebergdatabase-shokfev3ftjq`), which is not an expected pattern in a iceberg destination database (`/[a-zA-Z0-9\.\_]+/`).

It'd be great if the generated name does not contain hyphens.

Example CFn template (extracted)

### Other Details

Start with the extracted CloudFormation template, especially the AWS::Glue::Database resource and its Ref used by the Kinesis Firehose Iceberg destination. Reproduce the deployment and inspect how the auto-generated database name is formed; done means the generated name satisfies the Iceberg destination pattern without hyphens.
