Is there an existing issue for this?

Current Behavior

const optionGroup = new aws.rds.OptionGroup('psql-vector-testing', {
    engineName: 'postgres',
    majorEngineVersion: '17',
    optionGroupDescription: 'psql-vector-testing',
    options: [],
  }, options)

When running this pulumi code it fails with an error about not finding the major version, although the engine is supported (with v15) but also tried using that.

Expected Behavior

No errors, new OptionGroup created.

How are you starting LocalStack?

With the localstack script

Steps To Reproduce

import * as aws from '@pulumi/aws'

const optionGroup = new aws.rds.OptionGroup('psql-vector-testing', {
    engineName: 'postgres',
    majorEngineVersion: '17',
    optionGroupDescription: 'psql-vector-testing',
    options: [],
})

Running this pulumi code while running localstack with localstack start -d should give the mentioned error.

Environment

- OS: Ubuntu 22.04
- LocalStack: Pro
  LocalStack version: 4.3.0
  LocalStack CLI: 4.3.0
