### Regression Issue

### Last Known Working CDK Library Version

_No response_

### Expected Behavior

V3 should be supported in the cdk.

It is recommended to migrate from Timestream LiveAnalytics to Timestream Influx Db. Recently major changes were made from Influx Db from v2 to v3. It doesn't make sense to migrate from live analytics to v2, then later to v3. I am trying to do one migration from LiveAnalytics to v3, but v3 is not supported in the cdk.

### Current Behavior

With the recent release of InfluxDb V3 in AWS, it should be supported in the cdk.

If it is in progress, is there an expected date?
Timestream has had major changes lately, and it would be nice to know the timeline for support as the architecture keeps changing.

### Reproduction Steps

Create a CfnInfluxDBInstance in cdk.

### Possible Solution

Support v3 in cdk.

Start with the CfnInfluxDBInstance entry point and the AWS announcement linked in the issue. Compare the current CDK v2.220 support with the InfluxDB v3 requirements, then determine the scope needed for v3 support. Done means a CDK-defined CfnInfluxDBInstance can represent and deploy an InfluxDB v3 instance.
