Describe the bug

The generated IAM policy does not take into account if the service has a - in it's name for the IAM Policy Action

Expected Behavior

The generated IAM policy has the correct permissions

Current Behavior

The generated IAM policy does not has the correct permissions

Reproduction Steps

Given the following integ test

import * as integ from '@aws-cdk/integ-tests-alpha';
import * as cdk from 'aws-cdk-lib';

const app = new cdk.App();
const stack = new cdk.Stack();
const test = new integ.IntegTest(app, 'integ', {
  testCases: [stack],
});

const describeUsageLimit = test.assertions.awsApiCall('RedshiftServerless', 'getUsageLimit', {
  UsageLimitId: 'foo',
});

describeUsageLimit.expect(
  integ.ExpectedResult.objectLike({
    amount: 100,
    breachAction: 'deactivate',
    period: 'monthly',
  }),
);

app.synth();

An IAM Role with the following policy is generated with an incorrect action

    "Policies": [
     {
      "PolicyName": "Inline",
      "PolicyDocument": {
       "Version": "2012-10-17",
       "Statement": [
        {
         "Action": [
          "redshiftserverless:GetUsageLimit"
         ],
         "Effect": "Allow",
         "Resource": [
          "*"
         ]
        }
       ]

The action needs to be redshift-serverless:GetUsageLimit instead of redshiftserverless:GetUsageLimit
