chore(deps): bumping cdk from 1.78.0 to 1.83.0

[ryyakobe]

I deployed the all in AWS infrastructure basic app to confirm that everything is working.

Besides the CDK version bump, this includes:

• A change in usage-based-licensing.ts caused by the change in CDK fix(aws-ecs): update desired count to be optional aws-cdk#12223 . Our UsageBasedLicensing construct uses desiredCount not only for Ec2Service, but also for ASG. As we want these values to be the same, we won't be removing the DesiredCount similar to CDK, but will keep the same behavior as before, defaulting to 1. We do this, because if we don't set DesiredCount explicitly for the Service, it will use the current task number, but we won't be able to get this number for ASG from the service.

Remind me... what was the CDK change that required this change?

edit: n/m, I found it -- aws/aws-cdk#12223

The link and short description is in the description of this PR. There were 2 options available:

1. In RFDK we just default to size 1 if desiredCount is not set explicitly. (what I did in this PR)
2. Do not set any default in RFDK for Ec2Service. In this case CDK will not add DesiredCount property to the CloudFormation template. But then it's not clear what to use for minCapacity and maxCapacity in ASG here https://github.com/aws/aws-rfdk/blob/mainline/packages/aws-rfdk/lib/deadline/lib/usage-based-licensing.ts#L508, that's why I decided to go with a simpler option 1.
